How to open RadWindow in the script. I tried with show function. It is not opening. Thanks.

Answer 1

try this

  var oWnd = $find("<%=AddFavoriteRadWindow.ClientID%>");
    oWnd.show();

or alternate

    var oManager = GetRadWindowManager();       
    oManager.open(null, "AddFavoriteRadWindow");
