Jquery Div (Slide up and Slide down) Problem when asp.net button clicked

Hi,

I have the Div tag and I used Jquery show hide control. Initially the div was hide. When i click the some image I can show the div tag again I click the image I can hide the div tag.
My problem is when i click the image the div tag is slide up then i click any asp.net button then the page getting postback and the div tag is hide.
Should not hide the jquery slideup div when i click any asp.net button or link button.
Please help me to solve the problem.
Thanks in advance...
