I have implemented a form similar to that shown in the demo here:
In the main window I display a grid and when a row is selected in the grid I either open a rad window with detailed information in the form of another grid, or I refresh the grid in the radwindow grid, if it is already open. This is all ajaxified such that when this operation occurs, I see the RadAjaxLoadingPanel spinning when the radwindow data is being refreshed. However, most annoyingly, the radwindow disappears momentarily when during the refresh operation, in Internet Explorer. It doesn't seem to happen that way in Chrome, i.e., the window never disappears. Is this by design, and is there a way to prevent that?
