RadContextMenu ExpandDelay not working as expected

[Brian Gabel]

    <script type="text/javascript">
        function showCreateMenu(e) {
            var contextMenu = $find("<%= CreateMenuOptions.ClientID %>");

            if ((!e.relatedTarget) || (!$telerik.isDescendantOrSelf(contextMenu.get_element(), e.relatedTarget))) {
                contextMenu.show(e);
            }

            $telerik.cancelRawEvent(e);
        }

        function OnClientShowingHandler(sender, args) {
            var element = sender.get_contextMenuElement();
            var handler = function(e) {
                var relatedTarget = e.rawEvent.relatedTarget || e.rawEvent.toElement;
                if (!$telerik.isDescendantOrSelf(element, relatedTarget)) {
                    sender.hide();
                    $removeHandler(element, "mouseout", handler);
                    return;
                }
            };

            $addHandler(element, "mouseout", handler);
        }
    </script>

    <telerik:RadContextMenu ID="CreateMenuOptions" runat="server" OnClientShowing="OnClientShowingHandler" ExpandDelay="500">
        <Items>
            <telerik:RadMenuItem Text="Create Sales Order" Value="mnuCreateSO" />
            <telerik:RadMenuItem Text="Create Quote" Value="mnuCreateQuote" />
        </Items>
        <Targets>
            <telerik:ContextMenuControlTarget ControlID="CreateMenuOptions" />
        </Targets>
    </telerik:RadContextMenu>

    <asp:ImageButton ID="btnCreate" runat="server" CommandName="Create" onmouseover="showCreateMenu(event);" ImageUrl="~/images/toolbar_icon.png"></asp:ImageButton>

I have an ImageButton mouseover event which calls a JS function to show a RadContextMenu. This function works properly. However, the ExpandDelay setting of the RadContextMenu is not being used. When I mouseover the ImageButton the menu is displayed immediately. What can I do about this? I am using the 2009.1.402.35 controls.

Hello Brian,

The ExpandDelay property is intended to work only when the RadContextMenu is invoked by normal means, like right click. If you want to have delay when showing the RadContextMenu with javascript, please use setTimeout().

Thanks, Kamen, that will work.

    <script type="text/javascript">
        var timeoutId;

        function showCreateMenu(e) {

            if ((!e.relatedTarget) || (!$telerik.isDescendantOrSelf(contextMenu.get_element(), e.relatedTarget))) {
                contextMenu.show(e);
            }

            $telerik.cancelRawEvent(e);
        }
