When working on my asp.net webform, I incorporated an AgreementCheckBox along with a CustomValidator. However, I encountered an issue where the error message

Code for AgreementCheckBox:

 <asp:CheckBox ID="AgreementCheckBox" runat="server" ForeColor="Black" Text="Please agree to our terms and conditions!" />

Code for AgreementCustomValidator:

<asp:CustomValidator ID="AgreementCustomValidator" runat="server" ClientValidationFunction="AcceptTermsAndConditionsValidation" Display="Dynamic" 
  ErrorMessage="Please accept the terms and conditions!" ForeColor="Red"></asp:CustomValidator>

Server-Side Code:

 protected void AgreementCustomValidator_ServerValidate(object source, ServerValidateEventArgs args)
 {
 }

Please provide a potential solution, thank you....

Answer №1

When utilizing the CustomValidator feature, it is necessary to set e.IsValid to false within the event if the input is deemed invalid (additionally, verifying Page.IsValid upon form submission is crucial as ASP.NET does not automatically prevent form submission in case of validation errors). Your script may resemble the following snippet:

protected void ValidateAgreement(object sender, ServerValidateEventArgs e)
{
    e.IsValid = AgreementCheckBox.Checked;
}
