MenuAdv MVVM CanExecute does not work

Question

I bound an MenuItemAdv to an ICommand, and it works fine. The problem is the the CanExecuteMethod does execute, but has no effect. I tried this with both PRISM 8 and Syncfusion's implementation of DelegateCommand

If I use the WPF MenuItem, then the menu disables as expected.

Is this a bug or have I missed something?

Sulthan,Thank you for reply. It does look like the problem, but I cannot be sure since I bound my commands to a view model. Thank you for confirming the issue; I thought I may be using the control incorrectly.I installed the Syncfusion yesterday and the menu was the first control I tried. With this bug, I cannot use the menu for my project. I will not be spending any more time on this issue, and will be removing Syncfusion from my project, so I do not require a resolution.

Hi Syncfusion support,I'm wondering if this "the command binding related issue in Menuadv" has been fixed in the latest version? I'm having the similar issue. The MenuItemAdv did not change to enable when the

CanExecuteMethod excuted.

Regards,Yong

It does not. There is a work around. Do not use the "CanExecute" in the command but bind to the menu item's enabled property. Not ideal and requires a little more work, but it will do what you want.
