    Hello,
    I have a ASP.NET page with 5 RadComboBox. 
    When the user select one (and only one) item in the first Combo,
    I populate the other 4 Combos.
    Is there a way to place a cute spinning wheel - or anything similar - 
    that shows me operations on database in background?

    Thanks a lot.

    Luis

    Hello Luis,

    If you are triggering a Postback on each selection, you can use the AjaxManager or AjaxPanel to wrap the controls and add an AjaxLoadingPanel for them:

    If there is no postback, you can show and a loading panel programmatically:

    Hi Peter,
    in my aspx page I have this at the end of Form tag:

    <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" EnableAJAX="false" DefaultLoadingPanelID="RadAjaxLoadingPanel1">
          <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="cmbEdizione">
              <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="cmbFormati" LoadingPanelID="RadAjaxLoadingPanel1" />
                <telerik:AjaxUpdatedControl ControlID="cmbPosizioni" LoadingPanelID="RadAjaxLoadingPanel1" />
                <telerik:AjaxUpdatedControl ControlID="cmbSezioni" LoadingPanelID="RadAjaxLoadingPanel1" />
                <telerik:AjaxUpdatedControl ControlID="cmbTipologie" LoadingPanelID="RadAjaxLoadingPanel1" />
              </UpdatedControls>
            </telerik:AjaxSetting>
          </AjaxSettings>
        </telerik:RadAjaxManager>
        <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" />

     

    but nothing happen.

    I want that when the user selecteIndexChanged on the first comboBox (cmbEdizione), the other 4 - while fetch data from database - 
    have the spinning wheels above. 

    What I'm doing wrong? 

    Luigi

    Sorry my fault, it has EnableAjax = "False", and should be "True.
