validate radrating

[Sigma]

I have a radrating in my form. I want to validate whether the rating is checked using a customvalidator. Please help me to achieve this scenario.

Hi Sigma,

Try the following code snippet to achieve your scenario.

ASPX:

<telerik:RadRating ID="RadRating1" runat="server">
</telerik:RadRating>
<asp:CustomValidator ID="CustomValidator1" runat="server" ErrorMessage="Please rate"
    ControlToValidate="RadRating1" OnServerValidate="CustomValidator1_ServerValidate"
    ForeColor="Red">
</asp:CustomValidator>
<br />
<telerik:RadButton ID="RadButton1" runat="server" Text="RadButton">
</telerik:RadButton>

C#:

protected void CustomValidator1_ServerValidate(object source, ServerValidateEventArgs args)
{
    args.IsValid = (Int32.Parse(args.Value) > 0);
}

Please take a look into this documentation for more information.

Regards,
Princy.
