ExpandCollapse column for each detail table in hierarchial grid

[major]

I have a hierarchial grid where I display three detail tables for each parent record.
There is an expandCollapse column on the row of each parent record that the user can click on to display all three child tables.
I would like to know if I can JUST display the header names of each child table when a parent record is expanded. And each detail table header row will have an expandCollapse column to display the data.

INSTEAD OF THIS:
+  PARENT
        detail table header row
                details
        detail table header row
                details
        detail table header row
                details

I WANT THIS:
+  PARENT
        - detail table header row
        - detail table header row
        - detail table header row

[major]

anyone?

Hello,

The scenario which you describe is not a supported one by RadGrid. However, you can achieve similar look and functionality if you replace the detailtables with a NestedViewTemplate consisting of a RadPanelBar with two RadGrids in it. If you decide to do so, in order to optimize performance you can keep the RadPanelBar with Visible property set to false, until the row holding it is expanded. You can see what I mean in this forum post.
