when i click on search button it is asking me to fill the three text box for validation and it is not redirected to other page

You need to set the ValidationGroup properties on your textbox that has the validation and the joinnow button to the same thing. When you click the button it will validate controls in its group, and thus not validate from the search button (which is in a different validation group implicitly)

solution for it is 

set the property of the search button as below 

CausesValidation="False"
