confirmation message in asp.net2.0

Hi All,

I want to display confirmation message in aspx page with Ok and Cancel buttons.

When I click <asp:button, first .net validations has to be complete and then I should get confirmation message.

If user press Ok then some code has to be execute say Test1() and Cancel then nothing has to be executed.

I have tried with Message.show but it is not suitable for my project.

Any other way  for this Requirement?

Thanks,
...
