Hello friends,

I was developing a project in asp.net with c#, in this i've a button, when i click this button it will display a panel which consists of a gridview, textbox and some buttons. it is done by normal panel's property visible true/false.
It works fine but when i click the button it postback the entire page, one time two time is ok but every time it loads the entire page is sometimes irritates,

so i just want to know that is there any way to overcome this problem, that is without postback can i fire the button click event.

i tried UseSubmitBehavior=false but it was of no use..

I hope you understood my problem, Please help me to get rid of this problem.

Thank you.
