button and validators

I have a Table with two textboxes. Every textbox has a required validator to make the user insert data in the textbox.

I also have a Login table to confirm user privilages.

When I submit the button of login, the validators from the first table appear and prevent the user from logging in. I changed the login button property (Causes validation ) to false, but the validators which I added in the login table didn't appear.

So please how can I solve this problem.

Solution

I think you can solve your problem by using ValidationGroups. Here is an excerpt from a page with a longer explanation for you:

This page has two groups – a “Group1” and a “Group2” of validators. There are then two buttons on the page – when button1 is clicked, the first group of validators will fire. When button2 is clicked, the second group of validators will fire. Postback will be blocked client-side by default if the validation fails:

<html>
<body>
     <form runat=“server”>
          <asp:textbox id=“TextBox1” runat=“server”/>
          <asp:requiredfieldvalidator ValidationGroup=“Group1”
                                                       ErrorText=“Need to Fill in Value!”
                                                       ControlToValidate=“TextBox1”
                                                       runat=“server”/>
            <asp:textbox id=“TextBox2” runat=“server”/>
            <asp:requiredfieldvalidator ValidationGroup=“Group2”
                                                         ErrorText=“Need to Fill in Value!”
                                                         ControlToValidate=“TextBox2”
                                                         runat=“server”/>
            <asp:button text=“Group1” ValidationGroup=“Group1” runat=“server”/>
            <asp:button text=“Group2” ValidationGroup=“Group2” runat=“server”/>
     </form>
</body>
</html>
