Try to write more detailed questions. To get an answer, explain what exactly you see the problem, how to reproduce it, what you want to get as a result, etc. Give an example that clearly demonstrates the problem. If the question can be reformulated according to the rules set out in the certificate , edit it .

Do you use MVVM pattern? If yes, then:

 private ICommand _someCommand; public ICommand SomeCommand { get { if (_someCommand== null) _ledChangeCommand = new RelayCommand<string>(Picha_SaveFile); return _someCommand; } }

In the XAML markup:

 <Button x:Name="button" ... Command="{Binding SomeCommand}" CommandParameter="SomeParamater" />

If you do not use the MVVM pattern , then everything is much easier. Create a button on the form, give it a specific name and the following code:

 btn.Click += btn1_Click; private void btn1_Click(object sender, RoutedEventArgs e) { // Picha_SaveFile(); // }
