Hello
I would like to report a bug. If you put a RadComboBox in a RadWindow, you will not able to see the elements list. The same behaviour if you use a standard combobox with FormDecorator. Anyway you are still able to select items using keyboard.

This is the code:
<asp:ImageButton ID="cmdGraficoIstogramma" runat="server" ImageUrl="istogramma.png"
    OnClientClick="ApriGraficoIstogramma();return false;" ToolTip="Grafico Istogramma" />
<telerik:RadScriptBlock ID="RadScriptBlock2" runat="server">
 
    <script type="text/javascript">
            function ApriGraficoIstogramma() {
 
            var oWnd = $find("<%= RadWindow1.ClientID %>");
                        oWnd.show();
                        oWnd.maximize();
                        return false;
                }
         </script>
 
</telerik:RadScriptBlock>
<telerik:RadWindow ID="RadWindow1" runat="server" Title="Grafico a Torta"
    Width="800" Height="800" VisibleOnPageLoad="false" Behaviors="Maximize,Close"
    EnableShadow="true" InitialBehaviors="Maximize">
    <ContentTemplate>
        <telerik:RadComboBox runat="server" ID="cmbGraficoIstogrammaDimensione2" Skin="Office2007">
        <Items>
                    <telerik:RadComboBoxItem Text="Standard" Value="950x400" Selected="True" />
                   <telerik:RadComboBoxItem Text="Grandi" Value="1280x538"  />
                </Items>
        </telerik:RadComboBox>
    </ContentTemplate>
</telerik:RadWindow>

The element list box is rendered behind the window (if you minimize it you will see the list still opened).

Bye
Fabio

Hello fabio,

Here is the sample code that I tried which worked as expected.
aspx:
<telerik:RadWindowManager ID="mgr" runat="server">
  <Windows>
     <telerik:RadWindow  OpenerElementID="cmdGraficoIstogramma"   Modal="true"  Overlay="true" ID="RadWindow1" runat="server" Title="Grafico a Torta" >
        <ContentTemplate>
          <telerik:RadComboBox  runat="server"  ID="cmbGraficoIstogrammaDimensione2" >
            <Items>
               <telerik:RadComboBoxItem Text="Standard"  Value="950x400" Visible="true" Selected="True" />
                <telerik:RadComboBoxItem Text="Grandi" Value="1280x538" />
            </Items>
         </telerik:RadComboBox>
       </ContentTemplate>
    </telerik:RadWindow>
  </Windows>
</
telerik:RadWindowManager>
JS:
function OnClientClick()
 {
   var oWnd = $find("<%= RadWindow1.ClientID %>");
    oWnd.radopen(null, "RadWindow1");
}

Attached is the screenshot.

Hello,
I have made some tests. If you expand the RadWindow the issue will occur also in your example.... so it is related to the status of the window. It occurs also with RadTooltips (they are shown behind the window) :( I hope that there is a workaround because I really need radtooltips

Solution: ShowOnTopWhenMaximized="false"

Well, it is a workaround not a real solution... perhaps telerik should consider this particular case

Hello Mario,

In order to verify whether the experience behavior is a bug, please open a support ticket and provide a runnable sample page so we could reproduce it locally.

All the best,
