Hi there.
I've used Rad grid in my project and I have a problem with Hierarchical grid.
I have 3 hierarchies in my grid like this:
level-1
--------Level-2
-----------------Level-3
so as I read this link: http://demos.telerik.com/aspnet-ajax/grid/examples/programming/detailtabledatabind/defaultcs.aspx
all of data will be bind once.
I want to bind my SP by click
for instance I have my Level-1 which is bind in form_Load.
after clicking on + I want to fire my second SP to expand Level-2.
and after click on + in Level-2,I want to fire 3rd SP to expand Level-3.
I don't want to bind all of SPs once (I mean in form_load).
any idea?

Hi Vahid,
I would recommend you to do the initial binding on NeedDataSource, not on Form_Load. Also, if you keep the HierarchyLoadMode of all GridTableViews to ServerOnDemand, the DetailTableDataBind event will fire for each expanded item.
Kind regards,
