Hi,
I'm using RadEditor. All work good, but after inserting silverlight object some problem appears:
1. DialogWindow(Image Manager, Document Manager ...) shape was showen under silverlight object, at the same time content of this dialogs  is over silverlight
2. Toolbar dropdowns are also showen under silverlight

Help me please to solve this problem.

Here is the Html example:

<object width="739" height="433" data="data:application/x-silverlight-2," type="application/x-silverlight-2" style="width: 739px; height: 433px;">
<param name="source" value="/Silverlight/Example.xap"/>
<param name="windowless" value="false"/>
<param name="minRuntimeVersion" value="2.0.31005.0"/>
<param name="autoUpgrade" value="true"/><a href="http://go.microsoft.com/fwlink/?LinkID=124807" style="text-decoration: none;"><img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="Get Microsoft Silverlight" style="border-style: none;"></a></object><img alt="product logo" src="../../Img/productLogoLight.gif" />is the successor of the well known industry standard Editor for ASP.NET. The tight integration with ASP.NET AJAX and the powerful new capabilities make Telerik's WYSIWYG Editor a flexible and lightweight component, turning it into the fastest loading Web Editor. Among the hottest features are:
<ul>
    <li><em>Single-file, drag-and-drop deployment</em> </li>
    <li><em>Built on top of ASP.NET AJAX</em> </li>
    <li><em>Unmatched loading speed with new semantic rendering </em></li>
    <li><em>Full keyboard accessibility</em> </li>
    <li><em>Flexible Skinning mechanism</em> </li>
    <li><em>Simplified and intuitive toolbar configuration</em> </li>
    <li><em>Out-of-the-box XHTML-enabled output</em> </li>
</ul>

Hello Iurie,

In order to resolve the problem you should set windowless to true for the Silverlight object as shown below:


<object width="739" height="433" data="data:application/x-Silverlight-2," type="application/x-Silverlight-2"
    style="width: 739px; height: 433px;">
    <param name="source" value="/silverlight/Example.xap" />
    <param name="windowless" value="true" />
    <param name="minRuntimeVersion" value="2.0.31005.0" />
    <param name="autoUpgrade" value="true" />
    <a href="http://go.microsoft.com/fwlink/?LinkID=124807" style="text-decoration: none;">
        <img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="Get Microsoft Silverlight"
            style="border-style: none;"></a></object>

I tested this solution and it fixed the issue on my side. Please, test it on yours as well and let  me know how it goes.

Sincerely yours,

Thanks, this solution, to set <param name="windowless" value="true" />  resolve the problem, but oly partialy.

Windowless mode is useful to achive certain effects, but it has significant limitations. Therefore we use windowless mode only when it is necessary. In particular, complex animations and high defenition video content will not perform well in windowless mode.

Most our silverlight components work in windowless=false mode (<param name="windowless" value="false" /> ).

In my example only managers window is under silverlight, the content that is loaded into window is over. My be there is a solution to show and window over. We need 'windowless=false' more than 'windowless=true'.

Hi Iurie,

Unfortunately we cannot offer you another solution because the Silverlight object should be windowless in order to show a HTML element above it  and this is not directly related to RadControls but it is how the things work - you can test this with standard HTML elements as well and you will get the same result. The only other possible solution is to move the dialog not to be over the SL object but this will not lead to a very user friendly result because the expected behavior is to show the dialog centered on the page. Another solution is to change your layout so that the SL object will not be below the dialog.
