Dim colListData As New Collection

dsLists = wsListing.fndsGetListDataAll(Session("UserID"), Session("ListID"))

UltraWebGrid1.DisplayLayout.Pager.PageSize = 50

UltraWebGrid1.Width = Unit.Percentage(100)

UltraWebGrid1.Height = Unit.Percentage(100)

UltraWebGrid1.DisplayLayout.SelectTypeRowDefault = Infragistics.WebUI.UltraWebGrid.SelectType.Single

This calles a simple select * from and binds it.

Thanks.
