Solution 1

There is a property of the button, CausesValidation. Set it to false as:

<asp:Button ID="Button1" runat="server" Text="Button" CausesValidation="False"/>

Solution 2

Resolution 1:
Set the cancel button <code>CausesValidation</code> property to false

Resolution 2:
Use ValidationGroup attribute (of RequiredFieldValidator and all other controls you need to use for). Don't set this for cancel button.
