Changing display based on return from WebServiceSettings-Method

[Max]

Hello, I am very new to working with Telerik stuff.

I have a ComboBox that is a dropdown that gets populated from a WebServiceSettings-Method call (it querys our database and returns a RadComboBoxData object). I need to highlight some items in the dropdown with a color based on a flag in our database. I was wondering how to do this.

Is there an event that happens after a WebServiceSettings-Method call that I can hook on to?

Because if there is I can think of a way to do this.

In case anyone cares I hooked into OnClientItemDataBound and did

<telerik:RadComboBox [other things] OnClientItemDataBound="MarkFlaggedItems">

function MarkFlaggedItems(sender, eventArgs) {
    var item = eventArgs.get_item();
    var flag = item.get_attributes().getAttribute("Flag"); // Flag is a bool in the database
    if (loaded) { // if item has been flagged mark yellow
        item.get_element().style.backgroundColor = "yellow";
    }
}

I can't believe there's no edit on these forums. The "loaded" in the if statement is supposed to be "flag".
