delete a row from database using kendo MVC

public ActionResult ViewChangeLogs([DataSourceRequest] DataSourceRequest request) { List results = // whatever you do to get the items return Json(results.ToDataSourceResult(request)); // this does the paging }

That tells you exactly what you should do.

Add JsonRequestBehavior.AllowGet as a parameter to the Json() method.

I got an error when I change IQuerable to List.

This request has been blocked because sensitive information could be disclosed to third party web sites when this is used in a GET request. To allow GET requests, set JsonRequestBehavior to AllowGet.

Here is my controller code for above view code.
public ActionResult ManageUsers([DataSourceRequest]DataSourceRequest request, external_applications application, string appname)
{
        TempData["AppID"] = application.id;
        TempData["AppName"] = appname;
        IQueryable users = (from c in db.SP_ManageUsers() where c.appid == application.id                                         select c).AsQueryable();
        //return View(users.ToList());
        return Json(users.ToDataSourceResult(request));
}
I got an error "The result of a query cannot be enumerated more than once."

You can page server-side, but then you need to adjust something to this controller action: .Read(read => read.Action("ViewChangeLogs", "ExternalApplications"))

It would need to look something like this:

Here is my view code
@(Html.Kendo().Grid(Model)
.Name("grid")
.Columns(columns => {
columns.Bound(c => c.ad_user_id).Title("User").Groupable(false).HeaderHtmlAttributes(new { style = "font-size:18pt;" });
columns.Bound(c => c.title).Title("Title Description").HeaderHtmlAttributes(new { style = "font-size:18pt;" });
columns.Bound(c => c.date_created).ClientTemplate("#= kendo.toString(date_created,\"MM/dd/yyyy hh:mm:ss tt\") #").Title("Created Date").HeaderHtmlAttributes(new { style = "font-size:18pt;" });  columns.Template(@).ClientTemplate(@" ");
 .HtmlAttributes(new { style = "height: 380px;" })
.Scrollable() .Groupable() .Filterable()
.Sortable(sortable => sortable.AllowUnsort(true).SortMode(GridSortMode.MultipleColumn)) .Pageable(pageable => pageable .PageSizes(true) .ButtonCount(5))
.Resizable(resize => resize.Columns(true))
.DataSource(dataSource => dataSource
.Ajax()
.ServerOperation(false)
.PageSize(20)
.Batch(true)
.Model(model => model.Id(p => p.ad_user_id))
.Destroy(delete => delete.Action("Remove", "ExternalApplications"))
.Read(read => read.Action("ViewChangeLogs", "ExternalApplications"))
)
)

Have you tried an absolute path to your image? Is it copied to the right place when you build?

Here is my image code.


columns.Template(@).ClientTemplate(@" ");


Can you please give me the controller code for row delete operation.

I don't know what could be wrong with your image.

Using the class k-grid-delete triggers the delete command from the grid. I assumed you already had those events connected. This is what you would need to add:

You can use something like this:


@(Html.Kendo().Grid()
    .Name("grid")
    .Columns(columns =>
    {
        columns.Template(@).ClientTemplate(@"");
    })
)
