We are using Telerik Silverlight controls v2013.2.724.1050
When we navigate to the page first time control (RadTreeListView) load with column groups without any problem. Check Image attached.
After we navigate to another view and cause some action that should re-load grid data, this time data loads properly but without column groups.
What can we do to fix this issue?
We are loading group columns using code behind. Code snippet here ...
01.foreach(var headerColumn ingColumns)02. {03. _treeListView.ColumnGroups.Add(newGridViewColumnGroup()04. {05. Name = headerColumn.GroupName,06. Header = headerColumn.GroupHeader,07. HeaderTemplate = App.Current.Resources["GridViewColumnGroupHeaderTemplate"] asDataTemplate08. });09. }
I read this issue on forum and it mentioned that disabling EnableColumnGroupsVirtualization = false do the trick but I cant find that property anywhere even after including name space.
1.usingTelerik.Windows.Controls.GridView;
Can someone look at this and suggest some solution ... If you need more info on this please let me know.
