ContextMenu closes as soon as it opens on xamDialogWindow
posted

Hi,

I have placed text boxes and a XamDataGrid on a XamDialogWindow. I have set IsModal property of the XamDialogWindow to true and I have added ContextMenu On DataRecordPresenter of the grid.When I reight click on the grid, the contextMenu opens for a very brief time (few miliseconds) and then disappears. If the IsModal property is set to false, then it works just fine. I'm attaching a sample project. In this project my styling for XamDataGrid is done in XamDataGridStyle.xaml file. In ModalWindow if we put grid in scrollviewer. The scrollviewer contextmenu shows same behavior as well. A snapshot of snoop events for contextmenuopening and contextmenuclosing is also attached.
Your help will be appreciated.

    Hello Gottfried,

    Thank you for your post.

    I have been investigating into this issue and I have reproduced the behavior that you are seeing. Strangely, this appears to only happen with certain controls, such as the XamDataGrid. Placing a context menu on a Button element or something of the like seems to work correctly whether or not the dialog is modal. I am not entirely sure as of yet why the ContextMenu is closing instantly after being opened, but I am still investigating into this issue. I believe that the issue is likely happening because the ContextMenu itself is essentially a popup, and modal dialogs are meant to keep focus on themselves, so perhaps that is why the ContextMenu is not being opened.

    Something that is a bit strange is that the Infragistics context menu, the XamContextMenu, seems to work in this case. For the time being, I would recommend that you use the XamContextMenu instead of the built-in WPF one. You can read more about the XamContextMenu in our online documentation article about it, here: http://help.infragistics.com/doc/WPF/2016.1/CLR4.0/?page=xamContextMenu.html.

    I have also attached a sample project demonstrating the usage of a XamContextMenu on the DataRecordPresenter of a XamDataGrid. I hope this helps.

    Please let me know if you have any other questions or concerns on this matter.

    Sincerely,
