radiobuttonlist validation

I'm writing a custom validation for a radiobutton list (server-side), but it doesn't seem to be working.

Here is the radiobuttonlist code:

<asp:CustomValidator
ID="valxGuest"
runat="server"
ControlToValidate="rblGuest"
EnableClientScript="false"
SetFocusOnError="true"
ErrorMessage="Guest Attending?"
Display="dynamic"
Enabled="False" OnServerValidate="valxGuest_ServerValidate" ForeColor=""></asp:CustomValidator>
<label for="currcust" id="lblGuest" runat="server">Guest Attending?</label>
<asp:RadioButtonList
ID="rblGuest"
runat="server"
CssClass="radiolist"
RepeatColumns="2"
RepeatLayout="flow"
RepeatDirection="horizontal">
<asp:ListItem Selected="false" Text="Yes" Value="yes" />
<asp:ListItem Selected="false" Text="No" Value="no" />
</asp:RadioButtonList>

and here is the custom method I wrote to validate the radiobuttonlist:

protected void valxGuest_ServerValidate(object source, ServerValidateEventArgs args)
{
if (rblGuest.SelectedValue.ToString().ToLower() == "yes" || rblGuest.SelectedValue.ToString().ToLower() == "no")
{
args.IsValid = true;
}
else
{
args.IsValid = false;
}
}

Anyone see where I went wrong?

Thanks for any help.

Hi Carl,

Thanks for replying to my post. I just spotted the error:

I had:

I needed to remove the control to validate since it is a custom validator.

So, it should have been this:

It's working now.

Are you trying to force user to make at least one selection from the RadioButtonList?

Hi prairiedog,

yes, that is correct. At least one selection. It appears to be working okay now once I removed the ControlToValidate attribute.

You are reinventing the wheel. The built-in RequiredFieldValidator will do that for you.

Hmmm, I tried it with the required field validator and it did not work? I've used the required field validator many times, so I'm not sure what I would have done incorrect?

Here is what I used in my code:

<asp:RadioButtonList ID="RadioButtonList1" runat="server">
            <asp:ListItem>Yes</asp:ListItem>
            <asp:ListItem>No</asp:ListItem>
        </asp:RadioButtonList>
        <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="RadioButtonList1"
            ErrorMessage="Guest Attending?"></asp:RequiredFieldValidator>

Modified my RadionButtonList to exactly match yours. Still working.

<asp:RadioButtonList ID="RadioButtonList1" runat="server">
	<asp:ListItem Selected="false" Text="Yes" Value="yes"></asp:ListItem>
	<asp:ListItem Selected="false" Text="No" Value="no"></asp:ListItem>
</asp:RadioButtonList>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="RadioButtonList1"
	ErrorMessage="Guest Attending?"></asp:RequiredFieldValidator>
