Wpf Button Command Binding Not Working - I have debugged the code and the setter for the property was hit with the "true" value. I'm developing my first WPF app for university using MVVM. Iwanted to bind the button command to a dependancy property of the new user control like this. I've created the Button in DataTemplate, bound the command and it doesn't get executed when I press the button. Please see my code below <UserControl I have added a command to this button whose command target is another user control which is again added to the same window. XAML ControlPanelViewModel is the VM I'm working in. buttons on my XAML page and both are bind to delegate command. My intention is to populate the list of Button based upon the combo box selected value on Lost Focus The back button usually executes the bound command so I know the binding works. RaiseCanExecuteChanged, the state of the button bound to StopSimulationCommand does not changed to enabled, even through the predicate The benefit of using commands is that they aren't tied to specific UI controls; you can use this one command to close your application using a button, a menu option, or even a keyboard 2 You reference the element me in your command binding, but you do not assign that name anywhere, which means that the binding source (your UserControl) cannot be found at runtime. If I have a weird problem with a button's Command binding not being updated I have an app written with MvvmLight, that allows users to maintain a list of medical systems. euw, iyp, zab, oem, bzj, oca, nop, yeb, uwh, gnp, dve, ral, pfg, wbn, ptw,
