Hi guys,

I just got a issue with RadComboBox + RadAjaxManager.
The Scenaria:

Two cbb1 and cbb2 on the web page.
I use RadAjaxManager to update cbb2 when cbb1 posted back.
And when cbb1 selectedindex changed, pop up an new window.

but whatever I setup for RadAjaxManager the new window never popup.

<Format Code Block>
form id="form1" runat='server'>
             <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
             </telerik:RadScriptManager>
             <telerik:RadAjaxManager id="amgr1" runat="server" >
                  <AjaxSettings>

                     <telerik:AjaxSetting AjaxControlID="rcbbTest1">
                        <UpdatedControls>
                           <telerik:AjaxUpdatedControl ControlID="rcbbTest2" />
                           <telerik:AjaxUpdatedControl ControlID="rcbbTest1" />
                        </UpdatedControls>

         newWindowClient.NavigateUrl = url;
         newWindowClient.VisibleOnPageLoad = true; // Set the VisibleOnPageLoad to true

      }
</Format Code Block>

Thanks for your help

Hello Alex Zhang,

Please try the following:

1. Add a placeholder on your page:
<asp:PlaceHolder ID="place1" runat="server"></asp:PlaceHolder>

2. Set the AjaxSettings so the combo1 updates the place1 placeholder:

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="rcbbTest1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="rcbbTest2" />

<telerik:AjaxUpdatedControl ControlID="place1" />

</UpdatedControls>

</telerik:AjaxSetting>

3. Add the RadWindow object to that placeholder:

protected void rcbbTest1_OnSelectedIndexChanged(object sender, EventArgs e)

{

string url = "Request.aspx?subject='Request Client Access1'";

Telerik.Web.UI.RadWindow newWindowClient = new Telerik.Web.UI.RadWindow();

newWindowClient.NavigateUrl = url;

newWindowClient.VisibleOnPageLoad = true; // Set the VisibleOnPageLoad to true

newWindowClient.Title = "1";

place1.Controls.Add(newWindowClient);

}

Now, when you change the selection of the first combo - after the ajax request you will see the RadWindow.

All the best,
