    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 
      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,
