Remarks

BindCommand supports the WinForms MVVM pattern. Refer to the following help topic for additional information: Commands.

The following code snippet uses a command selector to bind a ViewModel command to a CheckButton:

C#

using DevExpress.Utils.MVVM;

var fluent = MVVMContext.OfType<MyViewModel>(mvvmContext);
fluent.BindCommand(checkButton1, vm => vm.SaveCommand());

VB.NET

Imports DevExpress.Utils.MVVM

Dim fluent = MVVMContext.OfType(Of MyViewModel)(mvvmContext)
fluent.BindCommand(checkButton1, Sub(vm) vm.SaveCommand())
