CustomValidator not adding error to ValidationSummary

[Guest]

We want to require a value for CboCharity if the value for cboCardSource =
Fundraiser. Here's the client script:

<script language="javascript">
<!--
function ValidateCharity(source, arguments)
{
frmRegister.cboCardSource.IsValid = true;
if (frmRegister.cboCardSource.value == "Fundraiser")
{
if (frmRegister.cboCharity.value == "")
{
frmRegister.cboCardSource.IsValid = false;
}
}
}

//-->
</script>

Here's the CustomValidator:

<asp:customvalidator id="valFundraiser" runat="server"
ErrorMessage="A Fundraiser must be selected" Font-Size="X-Small"
Font-Names="Arial" ControlToValidate="cboCardSource"
ClientValidationFunction="ValidateCharity" Display="None">
</asp:customvalidator>

When the value of cboCardSource = "Fundrasier" and the value of cboCharity =
"" the ValidateCharity client script function runs and cboCardSource.IsValid
is set to false, however the validation summary never includes the error for
cboCardSource: "A Fundraiser must be selected". Why?

The arguments parameter contains the IsValid property to set to true or
false. You are setting IsValid on the validator, not arguments.

function ValidateCharity(source, arguments)
{
arguments.IsValid = true;
if (frmRegister.cboCardSource.value == "Fundraiser")
{
if (frmRegister.cboCharity.value == "")
{
arguments.IsValid = false;
}
}
}
