Setting top row index

[Patrick Noble]

I am having some difficulty getting a specific row to appear at the top of a griddataboundgrid.
The grid just displays with the row at index position 0 whatever value I set in the code below.

gridCalls.DataSource = DsSchedule1.demand
gridCalls.SetTopRow(50)

Do I need to do something in addition?

Are you trying to do this in Form.Load before the grid is displayed? If so, before the initial display, a ListChanged.Reset event is raised for a DataTable DataSource, and this is causing the toprow to reset.

One way around this is to set a timer at the bottom of Form.Load to raise an event slightly later so you can reset the TopRowIndex after the ListChanged.Reset event has been handled.

''at bottom of form.load
Dim t As New Timer()
t.Interval = 1
AddHandler t.Tick, AddressOf t_Tick
t.Start()


''the handler
Private Sub t_Tick(sender As Object, e As EventArgs)
   Dim t As Timer = sender ''
   t.Stop()
   t.Dispose()
   t = Nothing
   
   Me.gridDataBoundGrid1.SetTopRow(50)
End Sub ''t_Tick

That was it.
Thanks Clay.
