I'm new to Asp.net MVC.
I have an application that manages users. My problem is that when I click on a delete link of a user row, the delete method has [AcceptVerbs(HttpVerbs.Post)] annotation is called automatically after a render delete method invoked. Thus, the user with id is deleted before I click on the delete confirm button and the error has occurred afterward.
Everything worked fine before. So, I don't know why this happend.
My code:
// GET: /User/Delete/5
[Authorize]
public ActionResult Delete(int id)
{
return View(GetByUserId(id));
}
// POST: /User/Delete/5
[Authorize]
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Delete(Users user)
{
//some process
}
The second method invokes automatically after the first one is called.
The view:
<h2>Delete</h2>
<p class="error"><%= Html.Encode(ViewData["messages"]) %></p>
<h3>Are you sure you want to delete this?</h3>
<fieldset>
<legend>Fields</legend>
<div class="display-label">UserId</div>
<div class="display-field"><%= Html.Encode(Model.UserId) %></div>
<div class="display-label">UserName</div>
<div class="display-field"><%= Html.Encode(Model.UserName) %></div>
<div class="display-label">FullName</div>
<div class="display-field"><%= Html.Encode(Model.FullName) %></div>
<div class="display-label">Email</div>
<div class="display-field"><%= Html.Encode(Model.Email) %></div>
<div class="display-label">DayOfBirth</div>
<div class="display-field"><%= Html.Encode(String.Format("{0:MM/dd/yyyy}", Model.DayOfBirth))%></div>
<div class="display-label">Phone</div>
<div class="display-field"><%= Html.Encode(Model.Phone) %></div>
<div class="display-label">Active</div>
<div class="display-field"><%= Html.Encode(Model.Active) %></div>
</fieldset>
<% using (Html.BeginForm()) { %>
<p>
<input type="submit" value="Delete" /> |
<%= Html.ActionLink("Back to List", "Index") %>
</p>
<% } %>
You can create another view which will solve your purpose of confirmation delete.

Above code is same as your code and it's working fine. Please have a look.

Using MVC 5, is it possible to have a button click event that updates a label on the same page?
For example, if I have a structure
#using (Html.BeginForm()) {
<fieldset>
<legend>Form</legend>
<p>
#Html.TextBox("textbox1")
</p>
<p>
#Html.Label("label1")
</p>
<p>
<input type="submit" value="Submit" />
</p>
</fieldset>
}
Clicking the Submit button grabs the textbox1's value, modifies it according to the function that gets called when the submit button is clicked and then update the value of the label as the result?
Assuming my controller is called TestController.cs and this is all done on the Index page
I noticed some suggestions include using AJAX (new to me)
You don't necessarily need to use AJAX for this. All you need to do is pass the value of your label back down as part of your action result e.g.
Controller
public class TestController : Controller
{
public ActionResult Index(string label)
{
// pass label value into view
return View("Index", label ?? "");
}
[HttpPost]
public ActionResult Index(string textValue)
{
// do something with textValue
// redirect to our Index action passing the new label value
return RedirectToAction("Index", textValue);
}
}
View
#model string
#using (Html.BeginForm()) {
<fieldset>
<legend>Form</legend>
<p>
#Html.TextBox("textbox1")
</p>
<p>
#Html.Label("label", Model)
</p>
<p>
<input type="submit" value="Submit" />
</p>
</fieldset>
}
The benefit of this approach is it follows the Post/Redirect/Get pattern so if you refreshed the page it wouldn't try to re-submit the form again.
Try this :
your cshtml code :
#using (Html.BeginForm()) {
<fieldset>
<legend>Form</legend>
<p>
<input type="text" id="textbox" name="textbox"/>
</p>
<p>
<lable id ="lable"></lable>
</p>
<p>
<input type="button" id="button" value="Submit" />
</p>
</fieldset>
}
jquery :
<script type="text/javascript">
$(document).ready(function(){
$("#button").click(function(){
document.getElementById("lable").innerHTML = $("#textbox").val();
});
});
</script>

Hopefully it works...!
Thanks.
You can also do it with Ajax by using
#Ajax.BeginForm();
helper. It would be more comfortable for end user.
I know the title of this question isn't very pretty. I dint have a better way to put it.
Lets look at the following code :
View for delete action:
#model LearningMVC.Models.Blog
#{
ViewBag.Title = "Delete";
}
<h2>Delete</h2>
<h3>Are you sure you want to delete this?</h3>
<fieldset>
<legend>Blog</legend>
<div class="display-label">
#Html.DisplayNameFor(model => model.URL)
</div>
<div class="display-field">
#Html.DisplayFor(model => model.URL)
</div>
</fieldset>
#using (Html.BeginForm()) {
<p>
<input type="submit" value="Delete" /> |
#Html.ActionLink("Back to List", "Index")
</p>
}
Controller action for delete action
[HttpPost, ActionName("Delete")]
public ActionResult DeleteConfirmed(int id)
{
Blog blog = db.Blogs.Find(id);
db.Blogs.Remove(blog);
db.SaveChanges();
return RedirectToAction("Index");
}
My questions is, How on earth this method got its parameter ?!
I am beginner in asp.net mvc . I am going to connect an action of button in view.
but i cant. i work with web form, in fact i want to click on the button, create action will be called and insert the data.
my code is as following:
The Controller:
namespace BookStore.Controllers
{
public class BookController : Controller
{
public ActionResult Create()
{
return View();
}
[HttpPost]
public ActionResult Create(book bookobj)
{
var dBook=new DBook();
dBook.Insertbook(bookobj);
return RedirectToAction("Index", "Home");
}
}
}
The View:
#model BookStore.Models.DomainObject.book
#{
ViewBag.Title = "Create";
}
<h2>insert data/h2>
#using(Html.BeginForm())
{
#Html.ValidationSummary(true);
<fieldset>
<div>
#Html.LabelFor(model=> model.book_name)
</div>
<div>
#Html.EditorFor(model => model.book_name)
</div>
<div>
#Html.LabelFor(model=>model.book_qty)
</div>
<div>
#Html.EditorFor(model=>model.book_qty)
</div>
<br/>
<div>
<input id="Button_craete_book" type="button" value="insert" />
</div>
</fieldset>
}
Change the button type to "submit":
<input id="Button_craete_book" type="submit" value="insert" />
That will post the form and values to the Edit method in the controller, as marked with the HttpPost attribute.
If I add data to table witch has no relationships, it's all good: data is adding. But if table have relationships, this is something wrong
Here is my project, what i mean is, for example AddSt in RouteController.
http://zalil.ru/32249903
Here is controller:
[HttpGet]
public ActionResult AddSt(int RouteId)
{
var routeDetails = (from rd in db.Route
join rdd in db.RouteDetail
on rd.RouteId equals rdd.Route.RouteId ///check
where rd.RouteId == RouteId
select rdd).FirstOrDefault();
return View(routeDetails);
}
[HttpPost]
public ActionResult AddSt(RouteDetail rd)
{
try
{
if (ModelState.IsValid)
{
db.AddToRouteDetail(rd);
db.SaveChanges();
return RedirectToAction("Index");
}
}
catch (Exception e)
{
ModelState.AddModelError("Error!", e);
}
return View();
}
and view:
<% using (Html.BeginForm("AddSt","Route")) {%>
<%= Html.ValidationSummary(true) %>
<fieldset>
<legend>Fields</legend>
<div class="editor-label">
</div>
<div class="editor-field">
<%= Html.TextBoxFor(model => model.Route.RouteId)%>
<%= Html.TextBoxFor(model => model.Station)%>
</div>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
<% } %>
Why I can't write model => model.RouteId ????
What's wrong?
Why TrainSheduleDBEntities table RouteDetail doesn't generate field RouteID ?
You are only selecting RouteDetail (rdd)
So you want model.RouteId
Just stick a debug on the addst action.
Have a look what's in rd.
I'm guessing that there's no valid routeid in it.
I have the following code in my aspx view page:
<% using (Html.BeginForm())
{
%>
<div>
CustomerCode:
<%= Html.TextBoxFor(x=> x.CustomerCode) %>
<%= Html.ValidationMessageFor(x => x.CustomerCode)%>
and this code in my model:
public class MyModel
{
[Required(ErrorMessage="customer code req")]
[StringLength(2,ErrorMessage="must be 2 u idiot")]
public string CustomerCode {get; set;}
Though if I enter more than 2 charachters in the textbox and submit the page, in the controller when I do:
if (ModelState.IsValid)
It always says its valid? What am I missing? I have put this MVC project inside a Web Forms project but the MVC project works fine, its just the validation which is not working, any ideas? Thanks.
Make sure that the controller action accepts the model as parameter:
public ActionResult SomeAction(MyModel model)
{
if (ModelState.IsValid)
{
}
return View();
}
Now if you invoke:
http://example.com/myapp/home/someaction?customercode=123
The model should not be valid.
Hmm, it works for me on a test page with the following
public ActionResult Test()
{
MyModel model = new MyModel();
return View(model);
}
[HttpPost]
public ActionResult Test(MyModel model)
{
if (ModelState.IsValid) { }
return View(model);
}
<% using (Html.BeginForm()) {%>
<%: Html.ValidationSummary(true) %>
<fieldset>
<legend>Fields</legend>
<div class="editor-label">
<%: Html.LabelFor(model => model.CustomerCode) %>
</div>
<div class="editor-field">
<%: Html.TextBoxFor(model => model.CustomerCode) %>
<%: Html.ValidationMessageFor(model => model.CustomerCode) %>
</div>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
<% } %>
public class MyModel
{
[Required(ErrorMessage = "customer code req")]
[StringLength(2, ErrorMessage = "must be 2 u idiot")]
public string CustomerCode { get; set; }
}
