Right-clicking opens and immediately closes RadContextMenu in FireFox 66 Quantum on MacOS
Hello guys,

 

We've faced an issue with menu on several RAD controls when running on MacOS 10.14.x (Mojave) with FireFox 66.0.x (Quantum).

Using touchpad or mouse, when right clicking for context menu, it just flashed and doesn't stay open: it opens and then suddenly closes.

We are using Telerik Asp.Net Ajax version 2017.2.503.40 but it can be also replicated on your demo version:

https://demos.telerik.com/aspnet-ajax/grid/examples/columns-rows/columns/context-menu/defaultcs.aspx

https://demos.telerik.com/aspnet-ajax/scheduler/examples/overview/defaultcs.aspx


Not sure if you can provide a fast workaround for this but I just wanted to let you know.

I've checked for some open cases before creating this thread and hope I didn't duplicate something. Please move/close it if necessary.

 

Regards,

Andrei V.

Update form 3 Oct 2019:

In Safari version 11.0(13604.1.38.1.6) both the right click and Ctrl+Left click show the Context Menu properly.

An update on the issue:

The Right-click event now works properly in both latest Safari and FireFox.

The remaining issue at the moment is the Ctrl+Left Click(an alternative to Right Click) in Safari, which is working properly in the latest FireFox.

Hi Andrey,

Thank you for bringing this to our attention. 

Indeed, there is a problem with the context menu event in the MacOS version of FireFox. The new update might change how the events are handled and the mouseup of the right click to act as a separate event, which causes the RadContextMenu to close.

A possible workaround when you are manually showing the menu using the show() or showAt() method would be calling the method in a 100ms timeout: 

<script>
    function f() {
        $telerik.$("#wrapper").click(function (ev) {
            var menu = $find("<%= RadContextMenu1.ClientID %>");
            menu.show(ev);
        });
        $telerik.$("#wrapper").on("contextmenu", function (ev) {
            var menu = $find("<%= RadContextMenu1.ClientID %>");
            setTimeout(function () {
                menu.show(ev);
            }, 100);
        });
        // Sys.Application.remove_load(f);
    }
    Sys.Application.add_load(f);
</script>

Once we have a more solid workaround or fix, we will share it here.
