IE not showing context menu

[Robert Bross]

I'm running into something very wierd with Internet Explorer. For some reason my context menu opens and then closes right away. When I attach code to the Showing, Hiding, Hidden, and Shown events, it goes in the following order: Showing, Shown, Hiding, Hidden. It never stops after it fires the shown event. (in Firefox it stops after the shown event and actually displays the context menu until I click somewhere else). When the Hidden event fires, I can actually see the context menu until I hit ok on that alert box and then it goes trhough the collapse animation. Here is the code that I am using...

<telerik:RadContextMenu ID="cmnuDesktop" runat="server"
                    OnClientShowing="cmnuDesktop_OnClientShowing"
                    OnClientHiding="cmnuDesktop_OnClientHiding"
                    OnClientShown="cmnuDesktop_OnClientShown"
                    OnClientHidden="cmnuDesktop_OnClientHidden"
                    >
                <Targets>
                    <telerik:ContextMenuElementTarget ElementID="windowContainer" />
               </Targets>
                <Items>
                    <telerik:RadMenuItem Text="Create New Folder" Value="newFolder" NavigateUrl="javascript: createNewFolder();"/>
                </Items>
            </telerik:RadContextMenu>

and the Javascript:

function cmnuDesktop_OnClientShowing(sender, args)
{
    alert("showing");
}

function cmnuDesktop_OnClientHiding(menu, args) {
    alert("hiding");
}

function cmnuDesktop_OnClientShown(menu, args) {
    alert("shown");
}

function cmnuDesktop_OnClientHidden(menu, args) {
    alert("hidden");
}

Has anyone else run into this issue before? The code works fine on Firefox, Opera, Chrome and Safari.

I just tried this using IE 8 with Developer tools and set the Browser version to IE 7 and now the context menus work again. So it must be something specific to IE 8. I also traced back through the stack trace/source and can see that there some code in _showAt function that is specifically handling an IE specific issue.

if (!this._detached)
        {
            this._detach();
            //IE: When initially located in an invisible element, the width is not calculated properly.
            this._getContextMenuElement().style.visibility = "hidden";
            this._getContextMenuElement().style.display = "block";
            this.repaint();
        }

I wonder if maybe there is an issue with it not detecting IE 8 as an IE browser and not doing some IE specific code that makes it work. Just thinking out loud. Not sure if this helps or not.

Hello Robert,

This is probably something related to your specific scenario as we haven't been able to reproduce the problem (for example on our live demos). What is the target ("windowContainer") of the Context Menu? Is it a RadControl or something else? If possible, can you please open a support ticket and send us a sample project that we can debug locally?

Thanks for your response Dimitar, However, I was able to finally isolate what the issue was. It was because I had another context menu attached the the same windowContainer. It was just really wierd how it worked in every browser except for IE and even in IE, it still showed the correct menu, it just collapsed it right away. Oh well, if anyone else runs into this issue, make sure that you check to see if there are any other context menus that are attached to the same control.
