Hello Abdallah,

I would suggest using a CustomValidator and writing the javascript to validate the control. Like so:

ASP.NET:
<asp:CustomValidator ID="CustomValidator1" runat="server" Display="Dynamic" ValidationGroup="Save"
                    ClientValidationFunction="ValidateRadComboBox">*<asp:CustomValidator>

JavaScript:
function ValidateRadComboBox(source, args){
    var combo = $find("RadComboBox1.ClientID");
      
    args.IsValid = combo.get_selectedIndex() > 0;
}

That's pretty much it. You'll need to handle the server-side check for the CustomValidator by handling the OnServerValidate event.

I hope that helps.

Hey Abdallah,

One thing that got me for a bit was that the RequiredFieldValidator works on the TEXT property of a RadComboBox, not on the Value property like a normal DropDownList.

It might be that you just need to change the InitialValue to something that represents the textual value of the default item.

Hope that helps,
Thad
