roundedcornersextender destroys size settings for contained Windows Media Player

All --

Please help.

I have a Ajax RC1 and VS.NET 2005 SP.

I have a roundedcornersextender applied to a Panel.

Inside the Panel, I have a Literal.

Based on an event firing, I load the Literal with an <object> tag that is a Windows Media Player control, dynamically set with all properties including height and width.

When the page loads, the Media Player is shown but its size is the size of the video playing, not the size set in the <object> tag.

Viewing the source of the page at run-time shows that the <object> tag does, in fact, have the custom settings 640x480, but the Media Player is being displayed on the page as 1024x768.

If the Literal is NOT in the Panel (and thus does not come into contact with the roundedcornersextended) then the Media Player is sized properly, 640x480, as set in the <object> tag.

Ideas?

Thoughts?

Guesses?

Please advise.

Thank you.

It sounds very strange that?the Media Player is shown as the size which is the size of the video playing, not the size set in the <object> tag.I once testedajax:RoundedCornersExtenderand didn't find this issue.Maybe this issue is caused by Media Player control. Try to place it outside of a asp:UpdatePanel and check if it works. Can you post some codes here? We'd like to test it.
Here are my simple testing codes about Ajax:RoundedCornersExtender.
<div>
<asp:Panel ID="pnlRoundedCorner" runat="server" BackColor="LimeGreen">
<table>
<tr><td id="RoundedCorner">Rounded Corner Rectangle:<asp:TextBox ID="TBRoundedCorner" runat="server"></asp:TextBox></td></tr>
</table>
</asp:Panel>
<Ajax:RoundedCornersExtender ID="RoundedCornersExtender1" runat="server" TargetControlID="pnlRoundedCorner" Radius="60"></Ajax:RoundedCornersExtender>
</div

OK.

I built a sample and posted it online, with all the source code, here...

http://www.WebLogicArts.com/DemoWindowsMediaPlayerAjax.aspx

...so that demonstrates the issue.

As you will see...

I have 2 cases there, one with Ajax and one without.

I have 2 Literals there, one inside a roundedcornersextender and one that is not.

I load each Literal with the exact same <object> tag code, which is Windows Media Player (WMP).

Without Ajax, the video does load in "small size", as specified by the <object> tag, where WMP's height and width is set.

With Ajax, the video does NOT load in "small size", as specified by the <object> tag, where WMP's height and width is set.

And so on.

Please let me know what you think.

Thank you.

   Purpose</h5>
  <ul>
   <li>The purpose of this demo is to present some code that shows a current issue (as of 2007-Jan-06) that I am having with Ajax and Windows Media Player (WMP). When WMP is loaded without Ajax, it is sized properly. When WMP is loaded with Ajax (inside a roundedcornersextender), it is not sized properly. See the code for details.</li>
