Hi,

         I have an editable grid within a user control being rendered from another user control which in turn are rendered from master page.

While the initial loading and display of the grid works fine, but when there is a post back of the page(Eg when a button is clicked) it throws the below error:

Error is thrown before the Server side event of click Button is triggered.

The ColumnSorted event is also not hit before the error is thrown.

DataBind happens in the page_load event of the user control  where we dynamically load the data into the WebDataGrid.

How to resolve this?

Index was outside the bounds of the array.

Server Side (Related to Sorting):

Protected Sub grdDataTable_SortColumn(sender As Object, e As SortingEventArgs) Handles grdDataTable.ColumnSorted
Dim i As Integer
Dim gridRefreshed As Boolean = False

RaiseEvent GridNeedsDataRefresh()
gridRefreshed = True

' 12/17/2004 BWM: Check if the grid was already refresh above, otherwise the it will be refreshed twice.
If grdDataTable.Behaviors.Paging.Enabled And Not gridRefreshed Then
RaiseEvent PagedGridNeedsDataRefresh()
End If
End Sub

Thanks,
