推荐答案

请参见以下链接:-

see the below link:-

Using Custom Validator to Validate Checkbox[^]

用于客户端验证的javascript函数(使用jQuery).

Hi,
javascript function for client side validation (using jQuery).

function CheckBoxRequired_ClientValidate(sender, e)
{
    e.IsValid = jQuery(".AcceptedAgreement input:checkbox").is(':checked');
}

用于服务器端验证的代码隐藏...

Code-behind for server side validation...

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

复选框&的ASP.Net代码验证器..

ASP.Net code for the checkbox & validator..

<asp:CheckBox runat="server" ID="MyCheckBox" CssClass="AcceptedAgreement" />
<asp:CustomValidator runat="server" ID="CheckBoxRequired" EnableClientScript="true"

    OnServerValidate="CheckBoxRequired_ServerValidate"

    ClientValidationFunction="CheckBoxRequired_ClientValidate">You must select this box to proceed.</asp:CustomValidator>

最后，在您的回发中-无论是通过按钮还是其他方式...

And finally, in your postback - whether from a button or whatever...

if (Page.IsValid)
{
    // your code here...
}

希望对您有所帮助.
