Hi Cheryl,

To set the size of grid, you need to handle the Grid.Model.QueryColWidth as explained in these KBs:

hello haneef
iv tried the following code :-

Private Sub Model_QueryColWidth(ByVal sender As Object, ByVal e As GridRowColSizeEventArgs)
Try
Dim clientsize As Int32
Dim gridsize As Integer = gdbgip.ClientSize.Width
Dim dbgmodel As Integer = gdbgip.Model.ColWidths.GetTotal(0, Me.gdbgip.DataBoundGridModel.ColCount)

clientsize = gridsize - dbgmodel

e.Size = clientsize / gdbgip.Model.ColCount

e.Handled = True

the problem is im getting the value in a msgbox but also system.stackoverflowexception:exception of type system.stackoverflowexception was thrown
Why is this happening ?

Hi Cheryl,

Even calling the ColWidths.GetTotal() within QueryColWidth event handler will trigger QueryColWidth event again leading to the recursive loop. You need to call the GetTotal() in Form''s load event.Here is a code snippet.

Dim dbgmodel As Integer

Private Sub Form_Load(ByVal sender As Object, ByVal e As EventArg)
dbgmodel = gdbgip.Model.ColWidths.GetTotal(0, Me.gdbgip.DataBoundGridModel.ColCount)
EndSub

Private Sub Model_QueryColWidth(ByVal sender As Object, ByVal e As GridRowColSizeEventArgs)
Try

Dim clientsize As Int32
Dim gridsize As Integer = gdbgip.ClientSize.Width
clientsize = gridsize - dbgmodel
e.Size = clientsize / gdbgip.Model.ColCount
e.Handled = True
gdbgip.Invalidate();

EndSub

Please let me know if this helps.
