I am trying to change the color of the header row when its in expanded mode. I tried the below code but didn't work.
Any other way?
Protected Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As GridItemEventArgs) Handles RadGrid1.ItemDataBound If TypeOf e.Item Is GridGroupHeaderItem Then Dim gpheader As GridGroupHeaderItem = CType(e.Item, GridGroupHeaderItem) If item.Selected Then gpheader.BackColor = Drawing.Color.DarkSeaGreen End IfEnd SubAny other way?

This is not right code or solution. There is no checking on whether group is expanded or not. You are only checking its a group row. Please don't put solutions without reading the questions.

Hello VIJAIANAND,
Have you looked at this code library thread? It points to a code library sample that should help you determine if the GroupRow Header is in an expanded state.
ExpandCollapseGroupedGridOnDoubleClickingTheGroupHeader
Hope this helps a bit.
Cheers!

That example gives an idea how I can do it but that incorporating "Dblclick" to invoke the expansion and identify its expanded or not. But a click event on the groupheader/groupsplitter column is already existing functionality. I thought it would be standalone property for the groupitem header to see whether expanded or not?

I was able to extract what I wanted it from the code snippet you provided and it works. Here you go,
Protected Sub RadGrid1_PreRender(ByVal sender As Object, ByVal e As EventArgs) Handles RadGrid1.PreRender For Each grphdr As GridGroupHeaderItem In RadGrid1.MasterTableView.GetItems(GridItemType.GroupHeader) If grphdr.Expanded Then grphdr.BackColor = Drawing.Color.DarkSeaGreen End If Next End Sub
