Button on click not working

Hi, Just check your property and event as Jitendra suggested you.

iam invoking the application from the system where XP Home edition of OS installed using the browser?

Hi,
Your question is not in understandable format.But these are the solutions.
1.Check you added runat="server" property to the button are not.
2.write the button click event in design mode. Don't write directly in code behind page if you are writing the code in c#.

if u click on a button for search after clicking nothing will be diplayed

nothing is happening after button click
