    Hi, I have a simple page with RadGrid above two RadListBox controls that are supposed to be populated with different items based on which item is selected in the grid.

    No matter what techniques I try, RadListBox controls appear to be empty on the page.  I am currently trying to use simple method shown here:

    http://www.telerik.com/help/aspnet-ajax/listbox-working-with-items-server-side.html

    Basically manually adding an object of type RadListBoxItem directly to the RadListBox in question, but the box remains empty on the page, any tips?  Maybe grid is throwing it off in some way?  How do I refresh it?

    Hi Bogdan,

    Is there a postback when you select a row in the Grid? If so, please wrap the Grid and two ListBoxes inside an UpdatePanel/RadAjaxPanel or add the following setting to RadAjaxManager - "Grid updates ListBox1 and ListBox2".

    Greetings,
