Add runat=server and you can do it the way you have posted.

<div  id="data1" class="division" style="visibility: hidden" runat="server">
</div>

Its becoming visible only for a second. how can i make visible permanently?

What are you doing with data1 in the code behind?

it contains just a section to display. and no code is written behind.

Try using display:none and display:block instead of visibility

This is a different issue, post a new question and include all of the relevant code.
