I have a RadListBox that is filled in the code behind when the SelectedIndex of a RadDropDown is changed. On the same screen is a button the will open a rad window that will allow the user to edit the information that is show in the RadListBox. I am trying to set up client side script that will reload the RadListBox when the RadWindow is closed. There does not seem to be a set_datasource. Is there anyway to do this?
