I have this in HomeController:
public ActionResult Details(string id)
{
var customer = Customers.GetCustomersById(id);
return PartialView("CustomerDetails", customer);
}
And this in Index.aspx:
<div>
<% using (Ajax.BeginForm("Details", new AjaxOptions
{
UpdateTargetId = "customerDetails",
InsertionMode = InsertionMode.Replace,
HttpMethod = "POST"
}))
{ %>
<p>
Customer:
<%=Html.DropDownList("id")%></p>
<p>
<input type="submit" value="Details" /></p>
<% } %>
</div>
<div id="customerDetails">
</div>
And finally in CustomerDetails.ascx I have:
<fieldset>
<legend>Fields</legend>
<p>
Name:
<%= Html.Encode(Model.Name) %>
</p>
<p>
Credit:
<%= Html.Encode(Model.Credit) %>
</p>
<p>
CustomerID:
<%= Html.Encode(Model.CustomerID) %>
</p>
</fieldset>
<p>
<%=Html.ActionLink("Edit", "Edit", new { /* id=Model.PrimaryKey */ }) %> |
<%=Html.ActionLink("Back to List", "Index") %>
</p>
CustomerDetails.ascx was generated by right clicking on the Details-method and choosing "Add View", and selecting partial view and strongly typed view.
I'd want this to update the customer details in "Ajax-manner" inside a div called "customerDetails" inside Index.html. The problem is that after pressing Details-button, a new page is opened where with the correct details. The output page has no master page colors or layouts.
If I debug at Details-method, the contents of customer object is correct.
Any help appreciated!

The most likely culprit is that you aren't including MicrosoftAjax.js and MicrosoftMvcAjax.js on the page. This causes the javascript to fail because it can't find the necessary functions and the form submits normally instead through Ajax.

What I am trying to do is I am Listing all the record and then provide option to delete the record. When User clicks on Delete Link on Index page he is redirected to Delete Confirmation Page( Delete View created by MVC framework), now what I was expecting was when I click on Submit button on the Delete View it will come to my Delete Action of Controller with the object that needs to be deleted. But the problem is I am getting a object but all the properties are set to null.
Below is the code:
//GET
public ActionResult DeleteUser (long id )
{
return View(_repository.GetUserById(id));
}
//POST
[HttpPost]
public ActionResult DeleteUser (UserDTO user)
{
_repository.DeleteUser(user.UserId);
/
return RedirectToAction("Index");
}
I was expecting that one submit is clicked then Second (HttpPost) method will be called and user will be filled with the values, but that is not happening..
can anyone tell me what wrong am I doing ???
This is my Delete View Code
<%# Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<RepositoryPatternSample.DTOs.UserDTO>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">

<h3>Are you sure you want to delete this?</h3>
<fieldset>
<legend>UserDTO</legend>
<div class="display-label">UserId</div>
<div class="display-field"><%: Model.UserId %></div>
<div class="display-label">Username</div>
<div class="display-field"><%: Model.Username %></div>
<div class="display-label">FirstName</div>
<div class="display-field"><%: Model.FirstName %></div>
<div class="display-label">LastName</div>
<div class="display-field"><%: Model.LastName %></div>
</fieldset>
<% using (Html.BeginForm()) { %>
<p>
<input type="submit" value="Delete User" /> |
<%: Html.ActionLink("Back to List", "Index") %>
</p>
<% } %>
</asp:Content>
Your properties are out of the form post. That's why you see the model null.
Personally instead of passing all the model properties I would pass only the id.
Something like that
<% using (Html.BeginForm()) { %>
<p>
<%: Html.HiddenFor(model=> model.UserId) %>
<input type="submit" value="Delete User" /> |
<%: Html.ActionLink("Back to List", "Index") %>
</p>
<% } %>
and your controller would be
[HttpPost]
public ActionResult DeleteUser (int userId)
{
_repository.DeleteUser(userId);
return RedirectToAction("Index");
}

can i apply some javascript or jquery here such that after click on submit button, it must checks for the values are valid , if can do so.
pls give code for the validation of last name field...this should not be empty.
i tried with this function but it dindt work....
protected void ValidateContact(ens.ContactPerson contactToValidate)
{
if (contactToValidate.FirstName.Trim().Length == 0)
ModelState.AddModelError("FirstName", "First name is required.");
if (contactToValidate.LastName.Trim().Length == 0)
ModelState.AddModelError("LastName", "Last name is required.");
if (contactToValidate.MiddleName.Trim().Length == 0)
ModelState.AddModelError("MiddleName", "Invalid phone number.");
if (contactToValidate.DateOfBirth.ToString().Trim().Length == 0)
ModelState.AddModelError("Email", "Invalid email address.");
}
Probably, You can force validate entire form with Sys.Mvc.FormContext.getValidationForForm. Example: http://weblogs.asp.net/imranbaloch/archive/2010/07/11/asp-net-mvc-client-side-validation-with-dynamic-contents.aspx
You will need some JavaScript references. Follow this http://www.gregshackles.com/2010/02/validating-hidden-fields-in-asp-net-mvc-2/
After that, you can just call any javascript method on submit button, do javascript validation and then submit the form.
<script type="text/javascript" language="javascript">
function ValidateLastName(name) {
//all validation here
var form = document.forms[0];
form.action = '/AddressType/Create';
form.submit();
}
</script>
OR may be one of these may help,

My Own javascript validation + MicrosoftMvcValidation . Is it possible ? How
You are going to want to make the submit button a regular button and onclick call a javascript function that validates your fields. If the validation passes you can submit the form with $("#myForm").submit(). You can do something like var lastName = $("#LastName").val() to get the value in your last name textbox and then test the value in lastName.
I have the following code in my HomeController:
public ActionResult Edit(int id)
{
var ArticleToEdit = (from m in _db.ArticleSet where m.storyId == id select m).First();
return View(ArticleToEdit);
}
[ValidateInput(false)]
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Edit(Article ArticleToEdit)
{
var originalArticle = (from m in _db.ArticleSet where m.storyId == ArticleToEdit.storyId select m).First();
if (!ModelState.IsValid)
return View(originalArticle);
_db.ApplyPropertyChanges(originalArticle.EntityKey.EntitySetName, ArticleToEdit);
_db.SaveChanges();
return RedirectToAction("Index");
}
And this is the view for the Edit method:
<% using (Html.BeginForm()) {%>
<fieldset>
<legend>Fields</legend>
<p>
<label for="headline">Headline</label>
<%= Html.TextBox("headline") %>
</p>
<p>
<label for="story">Story <span>( HTML Allowed )</span></label>
<%= Html.TextArea("story") %>
</p>
<p>
<label for="image">Image URL</label>
<%= Html.TextBox("image") %>
</p>
<p>
<input type="submit" value="Post" />
</p>
</fieldset>
<% } %>
When I hit the submit button I get the error: Sequence contains no elements on this line: var originalArticle = (from m in _db.ArticleSet where m.storyId == ArticleToEdit.storyId select m).First();
What is the problem? How do I fix it. Thanks
The problem is you have nothing that matches your linq query in _db.ArticleSet. First will throw against an empty collection.
Try FirstOrDefault() if returning null is ok. FirstOrDetault() will return null if nothing matches.
You are not including the ID of the article in your HTML form. If you debug the ArticleToEdit object is probably either null or has zero storyId.
You should include your storyId in the HTML form. You can do it as a hidden field if you don't want the user to see it. For example:
<% using (Html.BeginForm()) {%>
<%= Html.HiddenFor("storyId") %>
...
On a separate note, you should probably switch to using Single instead of First. First indicates that you want the First item in a collection. Single indicates that you should get one and only one result.
You need to be sure of is that when you're editing a record, you need to tell the database what record to edit. It's not enough to have the ID in the querystring unless you specifically tell the Model to use that ID (see my second option), however the easiest way to do that is add the field in your form.
<% using (Html.BeginForm()) {%>
<%= Html.HiddenFor("storyId") %>
<fieldset>
<legend>Fields</legend>
<p>
<label for="headline">Headline</label>
<%= Html.TextBox("headline") %>
</p>
<p>
<label for="story">Story <span>( HTML Allowed )</span></label>
<%= Html.TextArea("story") %>
</p>
<p>
<label for="image">Image URL</label>
<%= Html.TextBox("image") %>
</p>
<p>
<input type="submit" value="Post" />
</p>
</fieldset>
<% } %>
This second option shows how to specify the storyId after the fact by submitting it to the Action via the Querystring. You just have to make sure the form action includes ?storyId=[n]
[ValidateInput(false)]
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Edit(Article ArticleToEdit, int storyId)
{
ArticleToEdit.storyId = storyId;
if (ModelState.IsValid) {
_db.ApplyPropertyChanges(originalArticle.EntityKey.EntitySetName, ArticleToEdit);
_db.SaveChanges();
return RedirectToAction("Index");
} else {
return View(ArticleToEdit);
}
}
I would also suggest using something like AutoMapper to map ArticleToEdit to ArticleSet so that you don't need to make an additional DB lookup just to grab the original article. Basically if you are able to map ArticleToEdit to the ArticleSet Model, then you can use LINQ to SQL to perform the update without first querying for the storyId.
I am attempting to create a form where a user is able to enter your typical form values textboxes etc, but also upload a file as part of the form submission. This is my View code it can be seen that the File upload is identified by the MCF id:

}
return View(new ProblemFormViewModel(problem, assessmentExtension, staffMember));
}
This form was working correctly before I had to switch to using a non-AJAX file upload, this was due to an issue with Flash when enabling Windows Authentication which I need to use.
It appears that when I submit the form the file is not sent and I am unsure as to why? I have also been unsuccessful in finding an example online where a file upload is used in conjunction with other input types.
Another query I have is that for Create, and Edit operations I have used a PartialView for my forms to make my application have higher code reuse. The form action is normally generated by just using:
Html.BeginForm()
And this populates the action depending on which Url is being used Edit or Create. However when populating HTML attributes you have to provide a action and controller value to pass HTML attributes.
using (Html.BeginForm("Create", "Problem", FormMethod.Post, new { id = "ProblemForm", enctype = "multipart/form-data" }))
Is it possible to somehow populate the action and controller value depending on the URL to maintain code reuse? Thinking about it whilst typing this I could set two values in the original controller action request view data and then just populate the value using the viewdata values?
Any help on these two issues would be appreciated, I'm new to asp.net mvc :-)
Thanks,
Jon
ANSWER
Ok guys worked out the issue and its incredibly simple I didn't have the HTML name attribute on the file component of my form:
<input id="MCF" name="MCF" type="file" />
Now this binds to my method signature!
With the first issue, it looks like your action method signature is wrong. Because your fileInput has an ID of MCF, the HttpPostedFileBase parameter should have the same name so that the model binder knows to bind to that action method parameter.
E.g.
public ActionResult Create(Problem problem, AssessmentExtension assessmentExtension, Staff staffMember, HttpPostedFileBase mcf, string[] StaffEmail)
As for the second issue... you could try something like this:
<form method="post" id="ProblemForm" action="<%= Url.Action(ViewContext.RouteData.Values["action"].ToString()) %>" enctype="multipart/form-data">
The current controller will also be in RouteData.Values but if you're after the area, that'll be in RouteData.DataTokens.
HTHs,

I have a view with a grid that contains items added to a workstation. The user can select an item from a drop down list and click an action link which calls a controller that adds that item to the workstation. I can make it work by reading the FormCollection object in the Post action of the controller.
<p>
<% using(Html.BeginForm("AddItem", "Home")) { %>
<label for="ItemID">Item:</label>
<%= Html.DropDownList("ItemID", Model.ItemsList) %>
<%= Html.Hidden("WorkstationID", Model.Workstation.RecordID) %>
<input type="submit" value="Submit" />
<% } %>
</p>
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult AddItem(FormCollection formValue)
{
long workstationId = Convert.ToInt64(formValue["WorkstationID"]);
long itemId = Convert.ToInt64(formValue["ItemID"]);
Workstation workstation = itilRepository.FindWorkstation(workstationId);
Item item = itilRepository.FindItem(itemId);
itilRepository.AddItem(workstation, item);
itilRepository.Save();
return Content("Item added successfully!");
}
What I want to do is be able to submit the two parameters the workstationId and itemId to the controller using Ajax.ActionLink and have the new item that was added get inserted into the grid. I am rendering the grid like this:
<table>
<tr>
<th></th>
<th>
Name
</th>
<th>
Service Tag
</th>
<th>
Serial Number
</th>
</tr>
<% foreach (var item in Model.Items) { %>
<tr>
<td>
<%= Html.ActionLink("Edit", "ItemEdit", new { id = item.RecordID }) %> |
<%= Html.ActionLink("Details", "ItemDetails", new { id = item.RecordID })%>
</td>
<td>
<%= Html.Encode(item.Name) %>
</td>
<td>
<%= Html.Encode(item.ServiceTag) %>
</td>
<td>
<%= Html.Encode(item.SerialNumber) %>
</td>
</tr>
<% } %>
</table>
The problem I have is when I submit using the ActionLink I can't figure out how to pass in the parameters to the controller and how to update the grid without reloading the entire view.
I would really appreciate some help with this or even a link to a tutorials that does something similar.
Thank You!
This is the working version, the one problem is that when the controller returns the partial view that is all that gets rendred the actual page is gone.
<% using (Ajax.BeginForm("AddItem", null,
new AjaxOptions
{
UpdateTargetId = "ResultsGoHere",
InsertionMode = InsertionMode.Replace
},
new { #id = "itemForm" } ))
{ %>
<label for="ItemID">Item:</label>
<%= Html.DropDownList("itemId", Model.ItemsList) %>
<%= Html.Hidden("workstationId", Model.Workstation.RecordID) %>
Submit
<div id="ResultsGoHere">
<% Html.RenderPartial("WorkstationItems", Model.Items); %>
</div>
<% } %>
Not sure what the cause is, the replace was working correctly before but the controller wasn't getting the drop down value. Now the controller is getting the value but the partial view that is returned replaces the entire page.
The Action Method:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult AddItem(string workstationId, string itemId)
{
long lworkstationId = Convert.ToInt64(workstationId);
long litemId = Convert.ToInt64(itemId);
Workstation workstation = itilRepository.FindWorkstation(lworkstationId);
Item item = itilRepository.FindItem(litemId);
IQueryable<Item> items = itilRepository.AddItem(workstation, item);
itilRepository.Save();
return PartialView("WorkstationItems", items);
}
This is the HTML for the View that does all the work:
<%# Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<ITILDatabase.Models.WorkstationFormViewModel>" %>

What result are you expecting from the AJAX call?
You could use the AjaxHelper object's helper methods instead of the HtmlHelper to render the link. For example, to get new content with an AJAX HttpPOST call and insert it into a <div> with the id set to ResultsGoHere you render the following link:
<%= Ajax.ActionLink("Edit", "ItemEdit",
new {
itemId = item.RecordId,
workstationId = myWorkStationId
},
new AjaxOptions {
HttpMethod="POST",
UpdateTargetId="ResultsGoHere",
InsertionMode = InsertionMode.Replace
}) %>
In your AcionMethod, you can simply test on Request.IsAjaxRequest() to decide what to return:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult ItemEdit(string itemId, string workstationId) {
// edit the item and get it back
if (Request.IsAjaxRequest()) {
return PartialView("SingleItem", item);
}
return RedirectToAction("ItemEdit", new { itemId = item.RecordId, workstationId = workstationId });
}
// fallback for get requests
public ActionResult ItemEdit(string itemId, string workstationId)
{
// do stuff and return view
}
This is how you could do it using the Ajax.BeginForm() method instead:
<% using (Ajax.BeginForm("ItemEdit", null, new AjaxOptions
{
UpdateTargetId = "ResultsGoHere",
InsertionMode = InsertionMode.Replace
}, new { #id = "itemForm" } )
{ %>
<p>
<%= Html.DropDownList("itemId") %></p>
<p>
<%= Html.DropDownList("workstationId") %></p>
<p>
Submit
</p>
<% } %>
Please note that the code is in its current state in no way fully functional - the dropdownlists don't get their items from anywhere, there is no <div> to take care of the results from the AJAX request, and the onclick attribute on the link that submits the form requires that jQuery is included (in which case it is way better to give the link an id and add a click() event handler to it from a separate js file...)
EDIT: Oh, and I haven't verified that it is OK to pass a null value to the routeValues parameter. If not, just supply the controller and action names, and you'll be fine.
how can you pass the model from the view to the post create action of the controller using ajax.actionlink?
Here, as of my knowledge, we can pass data from View to Controller in two ways...
Using Formcollection built in keyword like this..
[HttpPost]
public string filter(FormCollection fc)
{
return "welcome to filtering : "+fc[0];
(or)
return "welcome to filtering : "+fc["here id of the control in view"];
}
FormCollection will work only when you click any button inside a form. In other cases it contains only empty data
Using model class
[HttpPost]
public string filter(classname cn)
{
return "welcome to filtering : "+cn.Empid+""+cn.Empname;
}
This is how you will be able to send multiple parameters through actionLink.
For this situation please refer to the code below:
#Html.ActionLink("Link text", "Action Name", null, routeValues: new { pram_serviceLine = Model.ServiceLine_ID, pram_Month = Model.Month, pram_Year = Model.Year, flag = "ROTATION" }
Reply if it works.
