How can I prevent RadGrid from refreshing when child TreeView node is expanded/collapsed?

[Carlos]

I have an ajaxified RadGrid with a RadTreeList in the <NestedViewTemplate>.  The data for both comes back as it should.  Expanding an item on the RadGrid works fine and reveals the RadTreeList with the correct number of rows/data; however, when attempting to expand one of the nodes on the RadTreeList, the RadGrid collapses.  On re-expanding the RadGrid, the RadTreeList node is displayed expanded.  How may I prevent the RadGrid from collapsing during the RadTreeList node expansion/collapse?

Thanks for the help!

Hi Carlos,

If you would like to store the currently loaded data on the server to prevent a 'full refresh', you would want to adjust the viewState (ASP.NET ViewState). There is a good demo which is on the Telerik website all about saving the viewstate of RadControls on the server-side. Try changing this setting and hopefully it will prevent the RadTreeList from refreshing the RadGrid.

Good luck,
Master Chief

Thanks for the reply!  I'll take a look at it.

Just thinking, though, shouldn't there be some other way to accomplish what I want?  I don't have this problem at all using a RadGrid within a <NestedViewTemplate> RadGrid.  That works perfectly fine.  Why is the radtreelist different?

any thoughts.. anyone?

Hi Carlos,

To be able to assist you about this problem we need to replicate it first. I suggest you to open a formal support ticket and send us a simple project which demonstrates your logic. We will examine it in details and will get back to you with additional information.

Thanks for the reply Pavlina!

Before I open a ticket, I would like to ask if what I am trying to do is even possible?  A radgrid that has a nested radtreelist with X number of tiers.

Appreciate the help!
