Hi! I had use the method of ViewDefinition. Where i can make column group.
The problem after the Grid show all my data its only read only... i can't do editing on particular row cell like normal.
Normally if i want particular columns is readonly then it won't able to edit. But with viewdefinition i didn't set any readonly via code.
May i know how can i do editing? Im using VB.NET 2010.
i code it like: http://www.telerik.com/help/winforms/gridview-viewdefinitions-column-groups-view.html
Hope to get the reply soon.
