[Solved] Inline Edit wont refresh on delete

[John]

Hi

I have a small issue with inline grid editing.  Everything appears to work as expected except for the delete.  The delete deletes the row from the database and returns the gridview less the row deleted but the gris does not refresh corrcetly.

Here is the defintion of the grid.

<%: Html.Telerik() _
                .Grid(Of AIMSModels.UserIPItemModel)() _
                .Name("UserIPSummaryGrid") _
                .DataKeys(Function(keys) keys.Add(Function(o) o.UserIpID)) _
                .ToolBar(Function(commands) commands.Insert().ButtonType(GridButtonType.Text)) _
                .Columns(Sub(columns)
                             columns.Bound(Function(o) o.IPStart).Width(150).Title("Starting IP Range")
                             columns.Bound(Function(o) o.IPEnd).Width(150).Title("Ending IP Range")
                             columns.Bound(Function(o) o.ScreenSaverID).Width(150).Title("Extended ScreenSaver").ClientTemplate("<#= ScreenSaver #>")
                             columns.Command(Sub(commands)
                                                 commands.Edit().ButtonType(GridButtonType.Text)
                                                 commands.Delete().ButtonType(GridButtonType.Text)
                                             End Sub)
                         End Sub) _
                .DataBinding(Sub(dataBinding)
                                 dataBinding.Ajax() _
                                     .Select("_AjaxUserIPSummary", "User") _
                                     .Insert("_AjaxUserIPInsert", "User", New With {.UserID = Model.UserID}) _
                                     .Update("_AjaxUserIPUpdate", "User", New With {.UserID = Model.UserID}) _
                                     .Delete("_AjaxUserIPDelete", "User", New With {.UserID = Model.UserID})
                             End Sub) _
                .Resizable(Function(resizing) resizing.Columns(True)) _
                .Scrollable(Function(scrolling) scrolling.Height(250)) _
                .Scrollable(Function(scrolling) scrolling.Enabled(True)) _
                .Editable(Function(editing) editing.Mode(GridEditMode.InLine)) _
                .ClientEvents(Function(events) events.OnEdit("onEdit")) _
                .Footer(True)%>

and  here is the delete code.

Function _AjaxUserIPDelete(ByVal id As Integer, ByVal Model As UserIPItemModel) As ActionResult
    Model.UserIpID = id
    Model.Delete()
    Return View(New GridModel(UserIPViewModel.GetUserIPItems(Model.UserID)))
End Function

I have checked the result set returned after the delete doesn't include the deleted row.  The only way to corrcet the grid so far is to click the refresh button.

Hope this is clear.

Hello John,

 Could you provide a sample project? Delete works as expected in our online demos and we are not sure what is different in your case.

Kind regards,

I have exactly the same problem!

I post it in http://www.telerik.com/community/forums/aspnet-mvc/grid/problem-with-grid-ajax-rebind.aspx

I have the issue in 2 places, one of them is on a RADWindow the othere is in a MVC Tab, the refresh after delete for some reason doesn't work.  I chedked the Ajax call and it is being triggered and returns the corrcet rows.  As Atanas requested we provide a sample which i plan to do by next week.  I will let you know if i find anything out.  Very strange as the samples work.

Did anyone ever find an answer to this issue. I came across the same issue today. I verified the JSON is correct but the grid does not refresh on delete. Add and Update work fine.

[EDIT] Never mind. If anyone else comes across this behavior, follow the suggestion in the link referred to earlier. http://www.telerik.com/community/forums/aspnet-mvc/grid/problem-with-grid-ajax-rebind.aspx

Almost certainly your model is throwing errors on validation. The easiest solution is to simply not use your model in your controller but pass in the item key property instead ("Id"). I had no particular reason to use a model parameter and it was there simply from a copy and paste. Change "public virtual ActionResult _Ajax_Delete(MyModel mm)" to "public virtual ActionResult _Ajax_Delete(Guid Id)" and you should be all set.

Hi

The issue for me has gone away and the code works as expected in both places.  The issue could have been solved by one of couple ofthings that has changed.

1. I am using the latest MVC release
2. I converted the project to C#, much better way to work att he end of the day as VB messed with the lambda expressions and also with VS2010 SP1 vb strted doing strange things
3. Upgrade to VS2010 SP1

I hope that helps anyone.
