How to override the auto-generated context menu on ribbon controls

Hello,

Thanks for reporting this.  It appears to be due to a change made in v18.1.  We have made some updates for the upcoming v22.1 that should allow custom ContextMenus on controls in the Ribbon again.

Thanks a lot in advance for fixing it! Do you know an aproximate release date for v22.1?

You're welcome!  We are aiming for November or early December.

Hi again!

I've just check this issue with the new version, 22.1, and it still there. My custom context menu does not override the QAT menu. Is there any workaround to suppress the QAT menu and show mine?

Hi Ilia,

I just pasted your original ribbon:Button sample code in our Ribbon demo in multiple places and added a Label to it so it shows up.  When I right click the instances, I see the context menu with the "Test" menu item and don't see our generated context menu with QAT-related items. 

Are you positive you are on v22.1?  Please test in our v22.1 Ribbon demo and if you still see a problem, let us know detailed steps to reproduce it.  Thanks!

Hi!

I double-checked it and I am surely using v22.1. It seems like the custom context menu works for <ribbon:Button> but does not for non-Ribbon custom controls.

Here I paste a code snippet that shows the issue:

 <ribbon:Ribbon IsToggleMinimizationButtonVisible="False">

        <ribbon:Tab Label="Test">
            
            <ribbon:Group>
                <ribbon:Button Label="Button">
                    <!-- this context Menu works -->
                    <ribbon:Button.ContextMenu>
                        <ContextMenu>
                            <MenuItem Header="Action 1" />
                        </ContextMenu>
                    </ribbon:Button.ContextMenu>
                </ribbon:Button>

                <Grid
                    Width="80"
                    Height="80"
                    Background="Green">
                    
                    <!-- this context Menu is ignored-->
                    <Grid.ContextMenu>
                        <ContextMenu>
                            <MenuItem Header="Action 1" />
                        </ContextMenu>
                    </Grid.ContextMenu>
                </Grid>                
            </ribbon:Group>
            
        </ribbon:Tab>

    </ribbon:Ribbon>

Hi Ilya,

Thanks for the updated sample.  We had to alter some logic to allow for non-Ribbon-oriented controls to support custom context menus.  The update for that will be in the next maintenance release.  That may not be for another month or more, so if you'd like a preview build to try out sooner, please write our support address and mention this thread.

Hi,

I would be definitly interested in a preview build, thank you!

Meanwhile, is there any simple workaround that I can use a temporal solution? For example, the Ribons docs mention that a context menu can be customized programmatically by intercepting the ContextMenuOpening. Would you recomend to try it?

ok, just figured out a simple solution for whom it might be interesting. First, I subscribed to OnContextMenuOpeningEvent as descibed here

There, I open the control's (Grid in this example) context menu programmically and cancel the QAT auto-generated menu with the following code:

 private void OnContextMenuOpeningEvent(object sender, ContextMenuEventArgs e)
            {           
            if (sender is Grid Gr)
                {                
                Gr.ContextMenu.PlacementTarget = Gr;
                Gr.ContextMenu.IsOpen = true;
                e.Handled = true; /// cancel the QAT menu
                }
            }

Hello,

Yes that would work.  If you'd like the preview build to try our code change, please so this update isn't needed, please write our support email address and reference this thread.  We will send you the preview build link privately.
