文本框Enter键事件在WPF中不起作用

Question

keydown事件无法正常工作。我想在按下回车键时引发与按钮相同的事件。这是C＃

    public partial class Search : Control
    {
        public SearchRevision()
        {
            InitializeComponent();
        }


        private void Button_Click_1(object sender, RoutedEventArgs e)
        {
            SearchViewModel vm = this.DataContext as SearchViewModel;
            if (vm != null)
                vm.Refresh();
        }

        private void myTextBox_KeyDown(Object sender, KeyEventArgs e)
        {
            if (e.Key == Key.Enter)
            {
                SearchViewModel vm = this.DataContext as SearchViewModel;
                if (vm != null)
                    vm.Refresh();
            }
        }

        private void myTextBox_Escape(Object sender, KeyEventArgs e)
        {
            if (e.Key == Key.Escape)
            {
                txtName.Text = "";
            }
        }
    }

Answer 1

在wpf中没有键码或keys.enter而是可以使用：

private void myTextBox_KeyDown(Object sender, KeyEventArgs e)
{
    if (e.Key == Key.Enter)
    {
        SearchViewModel vm = this.DataContext as SearchViewModel;
        if (vm != null)
            vm.Refresh();
    }
}

不需要写两次代码。你也可以这样做。

private void myTextBox_KeyDown(Object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Enter)
    {
        //you may pass the parameters if you need
        Button_Click_1(null,null);
    }
}
