[Srujan]

Hi Team ,

I am adding group by experissions progrmatically in my code and it is working as expected , I want to Expnad / Collpase selected group header , I am using below code in Item_Command and able to Collapse/Expand groups  as required but when I click next page Grid rebinds and grouping is lost , can you suggest how to go about this problem .

if (e.CommandName == RadGrid.ExpandCollapseCommandName)
 {
                GridGroupHeaderItem groupHeaderItem = (GridGroupHeaderItem)e.Item;
               
                if (groupHeaderItem.Expanded==true)
                    groupHeaderItem.Expanded = false;
                else
                    groupHeaderItem.Expanded = true;
}

Thanks

Hello Srujan,

Possible solution is to keep track of expanded/collapsed groups and expand/collapse them appropriately in ItemDataBound event handler.
I hope this helps.
