使用DevExpress XAF，我在“ ViewController ”中创建了“ Parametrizedaction ”，该条形码从barCode阅读器获取代码，然后在listView中添加新项。但是之后，parametrizedaction1失去了焦点，用户必须在阅读下一个条形码之前再次单击parametrizedaction1的文本。

现在，我想要的是执行结束后， Parametrizedaction中的文本将为空，并且 Parametrizedaction变得集中

public partial class TestViewController : ViewController
{
    public TestViewController()
    {
        InitializeComponent();
        // Target required Views (via the TargetXXX properties) and create their actions.
    }
    protected override void Onactivated()
    {
        base.Onactivated();
        // Perform various tasks depending on the target View.
    }
    protected override void OnViewControlsCreated()
    {
        base.OnViewControlsCreated();
        // access and customize the target View control.
    }
    protected override void OnDeactivated()
    {
        // Unsubscribe from previously subscribed events and release other references and resources.
        base.OnDeactivated();
    }

    private void parametrizedaction1_Execute(object sender,ParametrizedactionExecuteEventArgs e)
    {
        //Execution is made with success
        //No problem here
    }
}
