WPF: Binding to commands in code behind

The accepted answer will work great if the Button has access to the Command. However, in MVVM these are usually kept separate (the Button in the View and the Command in the View-Model). In XAML you'd normally use a data binding to hook it up (like the example in the question).

My program gave me an error when my dynamic Button couldn't find the Command (because it was in a totally different namespace). This is how I ended up solving this:

SurfaceButton.SetBinding (Button.CommandProperty, new Binding("SaveReservationCommand"));

Assuming that you have a named your SurfaceButton to "SurfaceButton1" and you have access to an instance of the command, you can use the following code:

SurfaceButton1.Command = SaveReservationCommand;

I took the code from the link posted by Anvaka as template. I use RadMenuItem of Telerik, but surely you can use any other component that expose Command property.

item = new RadMenuItem();item.Header = "Hide Column";DependencyProperty commProp = RadMenuItem.CommandProperty;if (!BindingOperations.IsDataBound(item, commProp)) {  Binding binding = new Binding("HideColumnCommand");  BindingOperations.SetBinding(item, commProp, binding);}//this is optional, i found easier to pass the direct ref of the parameter instead of another binding (it would be a binding to ElementName).item.CommandParameter = headerlCell.Column;menu.Items.Add(item);

Hope it helps ... and if something is not clear, sorry, it's my first post :)
