Execute Method (NavigateStateCommand)

Execute method performs the command. This method should be overriden to implement logic.

Syntax

public override void Execute( 
   object parameter
)

Parameters

parameter: The UI control

Remarks

The bound User Interface control executes the RoutedCommandBase.Execute() method to perform the logic associated with the command. This method should be overriden by the extending class to allow logic to be executed. By default this method performs no function.

Example

C#
XAML

private NavigateStateCommand mNavigateVisualState;

public NavigateStateCommand NavigateVisualState
{
    get
    {
        return mNavigateVisualState == null ? mNavigateVisualState = new NavigateStateCommand(this) : mNavigateVisualState;
    }
}
private QuitStateCommand mQuitVisualState;

public QuitStateCommand QuitVisualState
{
    get
    {
        return mQuitVisualState == null ? mQuitVisualState = new QuitStateCommand(this) : mQuitVisualState;
    }
}
