How to implement Validation Controls with multiple submit buttons

Question

There are two submit buttons on web form, Required field validation is there, i want if i click first submit button, it doesn't check the second submit. Mean i only want that only first text box Required validation must work? what should i have to do that i can segregate validation on multiple submit buttons For more detail, snap shot is included.

Answer 1

What you need is validationGroup property

The required Filed Validator will have following property

 <asp:requiredfieldvalidator id="RequiredFieldValidator2"
      ...
      validationgroup="Group1"
      ...
      runat="Server">
    </asp:requiredfieldvalidator>

And associated button

 <asp:button id="Button1" 
      text="Validate" 
      causesvalidation="true"
      validationgroup="Group1"
      runat="Server" />

In this way you can organise which validation to perform on any specific button click
