I originally posted this in the wrong forum.
==
Go to the RadWindow example 'Returning Values from a Dialog' and modify the DeafultCS.aspx file to add the following lines BEFORE the <qsf::footer ... tag.

<

table>
<tr><td>1</td></tr>
<tr><td>2</td></tr>

<tr><td>...</td></tr>
<tr><td>180</td></tr>
</table>

Add a total of 180 rows of data to the table.  When you view the page what you should see is that most of the page has the grey background but you can' tsee any of the content.  Additionally if you mouse over some of the elements you will see content show itself briefly.

This bug only appears to occur on IE7--Firefox 2 and Safari 3 seem to be ok.

Georgi,

I originally posted that in the RadControls for ASP.NET which was incorrect.  The bug actually occurs with the lastest Q1 release of ASP.NET Ajax release.

Did you test this with the Ajax.net release?

I'm attaching the complete source code for the file.  Just overlay this in your 'DialogReturnValue' directory.

Gerry

    The modal RadWindow object is set to reload each time it is being shown (using ReloadOnShow = true), so that its onload configuration handler would execute.
    By default, window pages are cached for improved performance, and are not reloaded when a window is made visible.

Hi Gerry,

I tested the problem with both ASP.NET and ASP.NET AJAX versions of the RadWindow control and everything worked as expected. I attached a small movie that shows what I see - can you please let me know if I am missing something?

Georgi,

What I see on my system is when I click on the button to display the dialog that the whole content page goes gray (I can not see anything) with the dialog mapped over this gray page.  If I mouse over the the text box or the buttons they show up but nothing else.

Are you testing this with IE7?  My version is 7.0.6001.17042.

If I could upload a photo I would send you my screen shot.

Thanks,
Gerry

Georgi,

Perhaps you could add more data to the table?  e.g. more rows?  I found that it depended upon the number of rows of data (if too few it wouldn't mess up).

ModalBackgroundTest.zip
Hi Gerry,

Yes, you are right - I was able to reproduce the problem locally with a table with about 3000 rows (I suspect it depends on the particular machine and the DirectX version that is used). The reason for the problem however is not in the RadWindow control but in the browser itself. To prove my point I prepared a small sample page without our controls where you can observe the same behavior. Basically the Javascript there does the same thing as when we are showing a modal RadWindow - it uses a DIV element with filtering to provide the semi-transparency.

Since this is a browser problem and we cannot fix it on our side, can you please let me know what is your exact, real-world scenario where you experiencing this problem? It will be best if you open a support ticket and send us a sample application which reproduces your setup. We will check it and try to find an appropriate workaround if possible.



Kind regards,

Georgi--please check ticket 137456.  I submitted a sample page with only about 200 rows of data.
