Using Q1 2010 and IE7. I have a RadTabStrip which is dynamically loaded on Page_Load. Each of the pageviews is created at this time with a user control. One of the user controls has a radSlider, which loads OK. However, when I mouse over one of the tabs, the rad slider just disappears. The slider's div is still there in the page source with the proper dimensions, but the slider is gone. When I change to another tab, it reappears until I mouse over a tab again. This only happens in IE7. The pageviews have already been setup with relative positions, so the slider does move when the pageview is scrolled.

Here is the code for the slider:
<telerik:RadSlider runat="server" ID="RadSlider1" Orientation="Horizontal" EnableAjaxSkinRendering="false"
                Skin="WebBlue" Height="40" TrackPosition="BottomRight" ItemType="Item" EnableServerSideRendering="false" TrackMouseWheel="False">
            </telerik:RadSlider>

The width is set on page_load when the items are loaded.

Hello Josh,
I created a simple page, based on the information you provided on your setup and tested it in IE7 with Q1 2010. I could not, however, reproduce the problem with the slider disappearing from the page. I have attached my test page for your reference - could you please open a new support ticket and send me a running test project that demonstrates this problem?

Hi Tsvetie,

Thanks for looking into this. I made a test project which reflects the structure of my page, and (naturally) the slider works perfectly in it. After trying several solutions, I finally decided to rebuild the user control from scratch because the slider worked properly in a blank control. Because of this, I found that the problem was somehow related to the fact that I had the slider sitting in a table cell. I moved it to its own div and it now no longer disappears.

Note: This problem happened in IE8 as well, except the slider disappeared right away after clicking on the tab and then moving the mouse.
Is there some javascript firing on the mouseover and mouseout of the tabstrip that could be conflicting with the client-side drawing of the slider?

Hello Josh,
I am not aware of a problem that would lead to the result you describe. You can use tools such as IE Developer Toolbar for IE or FireBug for FF to check whether the HTML of the control is created correctly, etc. In case you need additional help with that, please send me a running test project that demonstrates the problem.
