I have written code to implement search using ajax in asp.net MVC. I have written an action inside my controller (Admincontroller) using partial view which is supposed to fetch data. I want to display the partial view result inside table body in my Index page.
The search function is working fine, but it is not displaying the result inside table body with id "searchresult" (Inside Index page). instead of that it is giving result. I wanted the result from search in table format. now result is displayed like below in http://localhost:1274/Admin/Search.

here is my Index.cshtml
#model IEnumerable<TestEntityFramework.Models.trProducts>
#{
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_AdminLayout.cshtml";
AjaxOptions ajax = new AjaxOptions
{
UpdateTargetId = "searchresult",
Confirm = "Are you sure to start search?",
InsertionMode = InsertionMode.Replace,
LoadingElementId="Loadhere"
};
}

How to handle errors in Razor (i.e. Null Exception)other than (try/catch)?
I do not want to insert (try/catch) block in every razor block.
Example (The (Model.ListofEntity) or (Item.Values) may be null and an exception might occur):
<table class="table">
<tr>
<th>
<div id="chkCheckAll" class="divCheckbox">
</div>
</th>
#foreach (var column in Model.ListofEntity.Columns)
{
int t = Convert.ToInt32(" ");
<th>
#column
</th>
}
</tr>
#foreach (CVMEntities.Item Item in Model.ListofEntity.Items)
{
<tr>
<td>
<div id=#Item.ID class="divCheckbox">
</div>
</td>
#foreach (var Value in Item.Values)
{
<td>
#Value
</td>
}
</tr>
}
</table>
I have following view:
#model StockItemDetailModel
#using (Html.BeginForm("EditDetails", "StockItem"))
{
<div class="ItemDetails">
<table class="datagrid">
<tr>
<th colspan="3">#Model.StockItemPropertiesCaption</th>
</tr>
<tr>
<td class="label">#Model.StoreLabel</td>
<td class="value">#Html.DisplayFor(item => item.Store)</td>
<td></td>
</tr>
<tr>
<td class="label">#Model.BuildingLabel</td>
<td class="value">#Html.DevExpress().TextBoxFor(model => model.Building).GetHtml()</td>
<td class="validationError">#Html.ValidationMessageFor(model => model.Building)</td>
</tr>
...
<tr>
<td colspan="3">#Html.EditorFor(model => model.AmountModel, "Amounts")</td>
> </tr>
<tr>
<td colspan="3" class="validationError">#Html.ValidationMessageFor(model => model.AmountModel)</td>
</tr>
<tr />
</table>
</div>
<br />
<input type="submit" class="button" value="#Model.SaveButtonLabel" />
}
The partial View "Amounts" is as follows:
#model AmountModel
<table>
<tr>
<td class="label">#Model.AmountLabel</td>
<td class="value">
#Html.DevExpress().SpinEditFor(model => model.DenormalizedNetAmount,
settings =>
{
settings.Name = "DenormalizedNetAmount";
settings.Width = 153;
settings.Properties.DisplayFormatString = #"0.0,0";
settings.Number = 0;
}).GetHtml()
</td>
<td class="value">
#Html.DevExpress().ComboBoxFor(model => model.NetAmountUnit,
settings =>
{
settings.Name = "NetAmountUnit";
settings.Width = 60;
}).BindList(args => this.Model.AllUnits, args => this.Model.AllUnits).GetHtml()
</td>
</tr>
...
</table>
This is the AmountModel:
public class AmountModel
{
public decimal DenormalizedNetAmount { get; set; }
public string NetAmountUnit { get; set; }
...
public string AmountLabel
{
get { return i18n.StockItemDetailModel_AmountLabel; }
}
...
}
But the values of the input fields are not in the model in the Controller created by the model binder.
Why does the model binder not recognize the values in the editor template?
When I passed the FormCollection the values where correctly passed under the names "AmountModel.~"
public ActionResult EditDetails(FormCollection collection)
{
var netamount = collection["AmountModel.DenormalizedNetAmount"]; //correct value!
...
}
Do NOT specify the Name property when using the strong-typed (***For) helpers.
See the MVC Data Editors - Model Binding and Editing learning resource on the DevExpress forum.
Ive got a view that i pass a model to. I want it to render out a table out of a list in the model. It does that just fine it renders the view in that case that if i debugg it i can se the values goes to the right places. But the browser never updates. If i press ctrl+R in the browser it renders the view again in the exact same way but this time it show the list in the browser. Can i make this update everytime the view renders so that i don't have to press ctrl+R?
[HttpPost]
public ActionResult CreateResource(ViewModel view)
{
view.ResourceDateCreated = DateTime.Now;
viewmodel = view;
Session["ViewModel"]=viewmodel;
return View("Index", viewmodel);
}
The view:
<table class="table">
<tr>
<th>
MetaDataName
</th>
<th>
MetaDataDescription
</th>
<th>
LanguageCode
</th>
<th>
UserId
</th>
<th>
MetaDataDateCreated
</th>
#*<th>#Html.DisplayNameFor(model => model.MetaList)</th>*#
</tr>
#if (Model.Metadata.Count != 0)
{
foreach (var item in Model.Metadata)
{
<tr>
<td>
#item.MetaDataName
</td>
<td>
#item.MetaDataDescription
</td>
<td>
#item.LanguageCode
</td>
<td>
#item.UserId
</td>
<td>
#item.MetaDataDateCreated.ToString()
</td>
<td>
<table>
<tr>
<th>
MetaListId
</th>
</tr>
#if (item.MetaList.Count != 0)
{
foreach (var list in item.MetaList)
{

</tr>
}
}

</td>
</tr>
}
}

I'm creating a project for my institute. Using Asp.net MVC, I need multiple delete option with selected checkbox.
I have added a check in my view, but not delete multiple Raw. I don't want to use third party plugin. Please help me.
<table class="table table-striped table-condensed table-bordered">
<tr>
<th>
Select
</th>
<th>
#Html.ActionLink("Book Id", "Index", new { sortOrder = ViewBag.IdSortParm, currentFilter = ViewBag.CurrentFilter })
</th>
<th>
#Html.ActionLink("Title", "Index", new { sortOrder = ViewBag.NameSortParm, currentFilter = ViewBag.CurrentFilter })
</th>
<th>
#Html.ActionLink("Date", "Index", new { sortOrder = ViewBag.DateSortParm, currentFilter = ViewBag.CurrentFilter })
</th>
<th>
Price
</th>
<th>
Category
</th>
<th class="text-center">
Photo
</th>
<th>
User
</th>
<th>Edit</th>
<th>Delete</th>
</tr>
#foreach (var item in Model)
{
<tr>
<td>
<input type="checkbox" name="deleteInputs" value="#item.BookId" />
</td>
<td>
#Html.DisplayFor(modelItem => item.BookId)
</td>
<td>
#Html.ActionLink(item.BookTitle, "Details", new
{
id = item.BookId
})
</td>
<td>
#Html.DisplayFor(modelItem => item.PublishDate)
</td>
<td>
#Html.DisplayFor(modelItem => item.Price)
</td>
<td>
#Html.DisplayFor(modelItem => item.Category)
</td>
<td class="text-center">
<img class="img-thumbnail" width="50" height="50" src="~/ContentImages/Full/#item.Photo" />
</td>
<td>
#Html.DisplayFor(modelItem => item.UserName)
</td>
<td>
#Html.ActionLink("Edit", "Edit", new { id = item.BookId })
</td>
<td>
#Html.ActionLink("Delete", "Delete", new { id = item.BookId })
</td>
</tr>
}
</table>
This could be a way to achieve it:
First embed the table within a named form, that executes the batch delete action, like so:
#{ Html.BeginForm("BatchDelete", "Book", FormMethod.Post, new { name = "tableForm" }); }
<table class="table table-striped table-condensed table-bordered">
<tr>
<th>
Select
</th>
<th>
#Html.ActionLink("Book Id", "Index", new { sortOrder = ViewBag.IdSortParm, currentFilter = ViewBag.CurrentFilter })
</th>
<th>
#Html.ActionLink("Title", "Index", new { sortOrder = ViewBag.NameSortParm, currentFilter = ViewBag.CurrentFilter })
</th>
<th>
#Html.ActionLink("Date", "Index", new { sortOrder = ViewBag.DateSortParm, currentFilter = ViewBag.CurrentFilter })
</th>
<th>
Price
</th>
<th>
Category
</th>
<th class="text-center">
Photo
</th>
<th>
User
</th>
<th>Edit</th>
<th>Delete</th>
</tr>
#foreach (var item in Model)
{
<tr>
<td>
<input type="checkbox" name="deleteInputs" value="#item.BookId" />
</td>
<td>
#Html.DisplayFor(modelItem => item.BookId)
</td>
<td>
#Html.ActionLink(item.BookTitle, "Details", new
{
id = item.BookId
})
</td>
<td>
#Html.DisplayFor(modelItem => item.PublishDate)
</td>
<td>
#Html.DisplayFor(modelItem => item.Price)
</td>
<td>
#Html.DisplayFor(modelItem => item.Category)
</td>
<td class="text-center">
<img class="img-thumbnail" width="50" height="50" src="~/ContentImages/Full/#item.Photo" />
</td>
<td>
#Html.DisplayFor(modelItem => item.UserName)
</td>
<td>
#Html.ActionLink("Edit", "Edit", new { id = item.BookId })
</td>
<td>
#Html.ActionLink("Delete", "Delete", new { id = item.BookId })
</td>
</tr>
}
</table>
<!-- Section for buttons -->
<div class="actions">
<a href="javascript:(function(){document.tableForm.submit();return void(0);})()">
Delete selected books
</a>
</div>
#{ Html.EndForm(); }
Note that after the table, before ending the form, I added a link that executes the submit of the form.
Now, on the controller side, asumming its name is "BookController":
public class BookController : Controller
{
// ...
[HttpPost]
public ActionResult BatchDelete(int[] deleteInputs)
{
// You have your books IDs on the deleteInputs array
if (deleteInputs != null && deleteInputs.Length > 0)
{
// If there is any book to delete
// Perform your delete in the database or datasource HERE
}
// And finally, redirect to the action that lists the books
// (let's assume it's Index)
return RedirectToAction("Index");
}
// ...
}
Notice that:
The first two parameter of the Html.BeginForm method, are the action name and controller name (without the "Controller" suffix).
The last parameter of the same method include the name of the form. The name is used in the javascript of the link, in order to indicate which form are you going to submit.
First, you need a different Id for each checkbox so you know which record is to be deleted. Second, if you implement "delete" as a link then the browser will perform a GET action instead of a POST. Assuming you are not using AJAX then you will need a form so you can POST to the controller action which handles the delete.
