Hi,

In my WPF application, I have a parent window Main.xaml where i have a button. On click of button i want to open a new window ChildWindow.xaml through command (and not through click event in code behind)
when the child form open I want to disable the Main.xaml window so that user cannot click anything on it.

I need it through MVVM so creating ChildWindow instance in the viewmodel I am not looking for. Can anybody please help me out.

Solution 1

You can bind your button to a command using RelayCommand() and

have the child Window being opened from the ViewModel using the Application.Current.MainWindow property to link your new child window to the existing MainWindow.
