OnClientDropDownClosed

The OnClientDropDownClosed client-side event occurs after the drop-down list has been closed.

The event handler receives two parameters:

  1. The instance of the DropDownList firing the event.

  2. An eventArgs parameter which does not have methods.

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

<script type="text/javascript">
    function OnClientDropDownClosedHandler(sender, eventArgs) {
        alert("Dropdown is closed now");
    }
</script>

<telerik:RadDropDownList
    ID="RadDropDownList1"
    OnClientDropDownClosed="OnClientDropDownClosedHandler"
    runat="server">
    <Items>
        <telerik:DropDownListItem Text="Item 1" />
        <telerik:DropDownListItem Text="Item 2" />
        <telerik:DropDownListItem Text="Item 3" />
        <telerik:DropDownListItem Text="Item 4" />
    </Items>
</telerik:RadDropDownList>
