Question

我使用此代码创建Mahapps自定义对话框消息。问题是对话框窗体没有显示关闭按钮，所以无法关闭它。如何显示关闭按钮？

        public async void button_Click(object sender, RoutedEventArgs e)    

  {      Button btn = (Button) sender;
        //dialog.Resources["CustomDialogTest"];
        string[] id =  btn.Name.ToString().Split('_');

        this.MetroDialogOptions.ColorScheme = MetroDialogColorScheme.Accented;
        var dialog = (BaseMetroDialog)this.Resources["CustomDialogTest"];

        var mySettings = new MetroDialogSettings()
        {
            AffirmativeButtonText = "OK",
            AnimateShow = true,
            NegativeButtonText = "Go away!",
            FirstAuxiliaryButtonText = "Cancel",               
        };


         await this.ShowMetroDialogAsync(dialog);
         // this for close the dialog -> await this.HideMetroDialogAsync(dialog);           
    }

我需要一个自定义输入对话框。因此，我创建了一个继承自CustomInputDialog。{/ p>的BaseMetroDialog类

我使用此代码调用方法：

public async Task<string> ShowCustomDialog(string message, string title)
{
    var metroDialogSettings = new MetroDialogSettings()
    {
        AffirmativeButtonText = "OK",
        NegativeButtonText = "CANCEL",
        AnimateHide = true,
        AnimateShow = true,
        ColorScheme = MetroDialogColorScheme.Accented,
    };

    var dialog = new CustomInputDialog(View, metroDialogSettings)
    {
        Message = message,
        Title = title,
        Input = metroDialogSettings.DefaultText
    };

    return await InvokeOnCurrentDispatcher(async () =>
    {
        await View.ShowMetroDialogAsync(dialog, metroDialogSettings);

        await dialog.WaitForButtonPressAsync().ContinueWith((m) =>
        {
            InvokeOnCurrentDispatcher(() => View.HideMetroDialogAsync(dialog));
        });

        return dialog.Input;
    });
}

Message，Title和Input是CustomInputDialog的依赖项属性。这在我的最后工作。

在对话框中添加关闭按钮（位于Resources）＆amp;挂钩其Click事件以关闭对话框。要结束，请使用this.HideMetroDialogAsync(dialog); this为MetroWindow个实例。
