Slider Control not displaying in Fixed location

Hello,

I am creating a custom pager user Control for my app. It contains Ajax-ToolKit - Slider control in it. Everything works fine but there is an wierd display issues.

1. Whenever an postback happends in the Updatepanel, the Slider disappears and reappears

2. when you screen in the page, the Slider control is not in fixed location. I have placed the slider control inside a TR and applier css properties also.

Any thoughts?
