OnClientDropDownOpened

As of Q1 SP2, the RadComboBox exposes a new client-side event - OnClientDropDownOpened.

The OnClientDropDownOpened client-side event occurs after the drop-down list has been opened.

The event handler receives two parameters:

  1. The instance of the combobox firing the event.

  2. An eventArgs parameter containing the following method:

  • get_domEvent() returns the DOM event object of the drop-down opened.

You can use this event to perform any client-side actions when the drop-down is completely opened:

<script type="text/javascript">
    function OnClientDropDownOpenedHandler(sender, eventArgs) {
        alert("The dropdown is opened now");
    }
</script>
<telerik:radcombobox 
    id="RadComboBox1" 
    onclientdropdownopened="OnClientDropDownOpenedHandler"
    runat="server">
</telerik:radcombobox>
