Vaildation... sometimes

I have a textbox for a username, a bunch of other ones for other info, and two buttons at the bottom of the page: One to login and another that hides the current panel and shows another panel with information about creating a new account.

Now I want to have a required validation on the username box, so I add a required field validator, but the problem is that if the person wants to see the information panel instead of logining in they can't, they have to provide a username....

how do I avoid this?

Set the CausesValidation attribute on the button that hides/shows the panel to False.

VB Code:

<script language="vb" runat="server">
Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
 
End Sub 
Sub Login_Click(ByVal sender As Object, ByVal e As System.EventArgs)
    Response.Write("Logged in!")
End Sub 
Sub ShowSomething_Click(ByVal sender As Object, ByVal e As System.EventArgs)
    If Something.Visible Then
        Something.Visible = False
    Else
        Something.Visible = True
    End If
End Sub 
</script>
<html>
    <body>
        <form id="ConditionalValidation" runat="server">
            UserName:
            <asp:TextBox 
                ID="UserName" 
                Runat="server"/>
            <asp:RequiredFieldValidator 
                ID="UserNameRequired"
                Runat="server"
                ControlToValidate="UserName"
                ErrorMessage="*"
                ToolTip="UserName is required!"
                Display="Dynamic"/>
            <br />
            <asp:Button
                ID="Login"
                Runat="server"
                OnClick="Login_Click"
                Text="Login!"/>
            <asp:Button
                ID="ShowSomething"
                Runat="server"
                CausesValidation="False"
                OnClick="ShowSomething_Click"
                Text="Show Something"/>
            <br />
            <asp:Label
                Visible="False"
                ID="Something"
                Text="Here's Something!"
                Runat="server"/>
        </form>
    </body>
</html>
