not deleting a row using Kendo grid in mvc 5

Question

In MVC 5 application I am using Kendo grid. In that I insert delete button column , when I click the delete button in one row that entire row deleted from the grid not deleting from database when I refresh the page that deleted record still display in grid.

This is my view:

@(Html.Kendo().Grid(Model)

.Name("grid")

.Columns(columns =>

{

columns.Bound(c => c.ad_user_id).Title("User").HeaderHtmlAttributes(new { style = "font-size:20pt;" });

columns.Bound(c => c.title).Title("Title Description").HeaderHtmlAttributes(new { style = "font-size:20pt;" });

columns.Bound(c => c.date_created).Title("Created Date").HeaderHtmlAttributes(new { style = "font-size:20pt;" });

columns.Command(command => command.Destroy()).Width(110);

//columns.Template(e => { }).ClientTemplate("<img src='Content/images/delete.png'/>").Width(140);

})

.HtmlAttributes(new { style = "height: 380px;" })

.Scrollable()

.Groupable()

.Sortable(sortable => sortable.AllowUnsort(true).SortMode(GridSortMode.MultipleColumn))

.Pageable(pageable => pageable

.Refresh(true)

.PageSizes(true)

.ButtonCount(5))

.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"))

)

)

 

Controller code:

public ActionResult Remove(int? id, [DataSourceRequest] DataSourceRequest request, SP_ManageUsers_Result user)

{

var appEdit = GetApplicationDetailsByAppId(id);

if (user != null && ModelState.IsValid)

{

tbl_EA_AppUsers appUser = (from u in db.tbl_EA_AppUsers

where (u.appid == id)

select u).Single();

db.tbl_EA_AppUsers.Remove(appUser);

db.SaveChanges();

}

return Json(ModelState.ToDataSourceResult());

}

 

And how to add an delete image instead of delete button. when i click the delete image record will delete from grid and database also. this is my actual requirement. 

 

this is very urgent.

 

thank you,
