Can anyone point me to a sample of how to require entry into either of two
textboxes?

TIA
 
Hi,

Based on my understanding, your question is how to use validator to require
either one of two textboxes gets filled when submitted.

I think you can use a CustomValidator to do this:


WebForm:

<script type="text/javascript" language="javascript">
function check1(source, arguments)
{
arguments.IsValid = true;
if (form1.TextBox1.value == '' && form1.TextBox2.value == '')
arguments.IsValid = false;

}
</script>
</HEAD>
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
<asp:Button ID="Button1" runat="server" Text="Button"
OnClick="Button1_Click" />
<asp:CustomValidator ID="CustomValidator1" runat="server"
ErrorMessage="CustomValidator" ClientValidationFunction="check1"
EnableClientScript="true"
OnServerValidate="CustomValidator1_ServerValidate"></asp:CustomValidator></d
iv>


Code-behind:

protected void CustomValidator1_ServerValidate(object source,
ServerValidateEventArgs args)
{
args.IsValid = true;
if (TextBox1.Text == "" && TextBox2.Text == "") args.IsValid = false;
}
protected void Button1_Click(object sender, EventArgs e)
{
Response.Write(Page.IsValid);
}


If the client browser has enabled javascript, the validation will be done
on client-side; otherwise the server-side event ServerValidate will check
the two textboxes.
