Standard Grid via LINQ DS
<telerik:GridButtonColumn ButtonType="ImageButton" CommandName="Delete" ConfirmDialogType="RadWindow" ConfirmText="Are you sure? Delete means delete." />

Protected Sub ReportGrid_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles ReportGrid.ItemCommand

If e.CommandName = "Delete" Then

Dim filepath As String = (CType(e.Item, GridDataItem)).OwnerTableView.DataKeyValues(e.Item.ItemIndex)("Doc_Path").ToString

If System.IO.File.Exists(Server.MapPath("/Files/" & filepath)) Then

System.IO.File.Delete(Server.MapPath("/Files/" & filepath))

End If

End Sub

Fires every time faithfully in IE 7. In FF 4.0 it fails miserably. Ideas/Workarounds?

RadGrid issue when using on Sitefinity

Hi,

We have created a user control which has one radgrid control. The paging/sorting/filtering works well when tested locally.
But when we upload the user control to sitefinity site, the radgrid binds the data correctly but paging/sorting/filtering does not work.
On clicking on these options, it does a post back but no change on the grid.

Can you please help us figure out the issue?

Thank you,
Jay Mehta.

REQUEST: New Grid Event for OnLoad

We would like to request a new server-side event for the RadGrid. Please add an event called OnLoad or AfterNewBinding. The purpose of this event would be to fire after the grid has been loaded with data. At this point, it is not easy to detect when the datasource's data has changed on the grid so we can select the first row. We can't use pre-render event as the data has not yet been populated. We also tried the ObjectDataSource's Selected event and the data has not been loaded either.

If we had an event which fired after any new data has been bound and loaded, this would be easy.

Thank you for your consideration.
