Solution 1

Make a validation function at code behind. As you said the textbox value may or may not be mandatory.
So write code as per your requirement.

Solution 4

solution is pretty simple use CausesValidation="false" in asp:button
or write like this
<input type="button" onclick="validation();return false;"/>
<asp:Button id="aa" runat="server" onclick="fadf" onClientClick="validation();return false;"/>
