Disabling ComboBox on the Client Doesn't Change Appearance

[Brian Mains]

Hello,

I'm trying to disable the combo box on the client, and having it look disabled (using the italicized font, which I have been able to setup).  I manually invoke the requesting of items from the web service, and on the itemsrequested client-side event, I do this:

function

 

itemsRequested(sender, e) {

 

 

  if (sender.get_items().get_count() == 0) {

 

       sender.set_enabled(

false);

 

 

        return;

 

  }

}

This actually runs, but the UI of the combo doesn't change to the new style...  do I have to programmably do it?

Thanks.

Hello Brian Mains,

I can suggest you disable RadComboBox at the client using disable() method.

If you prefer to modify some of the style properties of the RadComboBox at its "disabled" state, you can follow this approach:

function itemsRequested(sender, e) {

    if (sender.get_items().get_count() == 0) {

        sender.disable();
        var inputArea = sender.get_inputDomElement();
        inputArea.style.color = "gray";
        inputArea.style.backgroundColor = "#cccccc";
        inputArea.style.fontWeight = "bold";

        return;
    }

}

Please let me know if this was helpful.
