Question

I have a requirement that one of multiple fields is required. Using custom validator the even fires, false is returned, but no error message is display and the form validates.

What am I missing? I have tried with and without ValidationSummary.

Thanks!

<asp:CustomValidator ID="CustomValidator1" OnServerValidate="validatePhone" EnableClientScript="false" runat="server" ErrorMessage="Home or Cell Phone is Required" ></asp:CustomValidator>

<asp:ValidationSummary ID="ValidationSummary1" DisplayMode="BulletList"  runat="server" ForeColor="Red" Font-Size="X-Small" Font-Bold="true" />


protected void validatePhone(object sender, ServerValidateEventArgs e)
    {
        e.IsValid = string.IsNullOrEmpty(txtCellPhone.Text) && string.IsNullOrEmpty(txtHomePhone.Text) ? false : true;
    }

Answer 1

Issue was completely my fault. On my submit button the final thing I do is a Response.Redirect. The message was coming up, but then the Thank you page was being presented. Now only doing the Response.Redirect if the customvalidator returns true.
