How to Bind a Command in WPF
- by MegaMind
Sometimes we used complex ways so many times, we forgot the simplest ways to do the task.
I know how to do command binding, but i always use same approach.
Create a class that implements ICommand interface and from the view model i create new instance of that class and binding works like a charm.
This is the code that i used for command binding
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
DataContext = this;
testCommand = new MeCommand(processor);
}
ICommand testCommand;
public ICommand test
{
get { return testCommand; }
}
public void processor()
{
MessageBox.Show("hello world");
}
}
public class MeCommand : ICommand
{
public delegate void ExecuteMethod();
private ExecuteMethod meth;
public MeCommand(ExecuteMethod exec)
{
meth = exec;
}
public bool CanExecute(object parameter)
{
return false;
}
public event EventHandler CanExecuteChanged;
public void Execute(object parameter)
{
meth();
}
}
But i want to know the basic way to do this, no third party dll no new class creation. Do this simple command binding using a single class. Actual class implements from ICommand interface and do the work.
