[Solved] Hierarchy - Limit to a single expanded row

[Jason]

Hi,

I would like to limit the number of rows expandable in my grid to a single row.  My solution has a RadGrid with a NestedViewTemplate.  When a user selects the row and it is expanded I'd like to collapse any other rows that are already expanded. 

I'd like to do that on the client side before the new row is expanded and databound.  I've tried the client-event OnGroupExpanded but thats not the event being fired.

Thanks
Jase

Hi,

I've found the client-event OnHierarchyExpanding.  But I could do with some help putting the javascript together.

Thanks
Jase

Hello Jason,

I recommend you try the following approach:
Single expand in hierarchical grid

Let me know whether this helps.
