Dear Telerik-Support
I set up a RadGrid with SelfHierarchySettings. Everything works fine. The hierarchy will shown as expected.
Then I allow filtering on some columns. The problem is that the default filter (it.PrentId == null from Page_Load()) to show only the root items will be lost and according to this all items (also the child items) will be shown in the grid after the user fire a column filter.
How can I add the default filter (it.PrentId == null from Page_Load()) to all filter events that are fired against the grid/datasource? So witch event is the right one to manipulate the filterExpression or filterExpressions to add a default filter before the datasource will be filtered based on this manipulated filters.
Please see my attched files.
Kind regards,
Chrsitian

Hello Uwe,
You can find a sample project that demonstrates how to implement this functionality in the following forum thread:
