When I click on  btnAssignId, grdResult has 4 rows, but in debug mode in loop I see 5 iterations and on 5th Exeption throw
at line where I try GetDataKeyValue



Private Sub btnAssignId_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAssignExistingId.Click
  If Not String.IsNullOrEmpty(tbMatlID.SelectedValue) Then
    For Each item As GridItem In grdResult.Items
      If item IsNot Nothing Then
        Dim griddata = CType(item, GridDataItem)
   Dim resultId griddata.GetDataKeyValue("ResultId")
        Update(resultId, tbMatlID.SelectedValue)
      End If 
    Next
  End If
End Sub

Hello Bogdan,

I have created a sample RadGrid web site to test the described behavior. On my side everything works as expected and the the items collection returns the correct count. Please check out the attached application and let me know about the result.

Kind regards,

In my case, it is because the last page of grid has less items than the page size. For example, if the page size is 10, but the last page only have 5 items. Then it will throw this IndexOutOfRange Exception in method GetDataKeyValue.

I'm lazy, so I just try-catch that line
