如何在
Windows Phone 7中创建确认对话框？
我有一个应用程序,我可以删除项目,但当有人点击删除,我想让他一个确认对话框,他们可以点击’确认’或’中止’
我怎么能这样做？
这是我使用的方法.为了获得更好的用户体验和一致性,请考虑使用“删除”和“取消”而不是“确认”或“中止”.
public static MessagePromptResult Show(string messageBoxText,string caption,string button1,string button2)
{
int? returned = null;
using (var mre = new System.Threading.ManualResetEvent(false))
{
string[] buttons;
if (button2 == null)
buttons = new string[] { button1 };
else
buttons = new string[] { button1,button2 };
Microsoft.Xna.Framework.GamerServices.Guide.BeginShowMessageBox(
caption,messageBoxText,buttons,// can choose which button has the focus
Microsoft.Xna.Framework.GamerServices.MessageBoxIcon.None,// can play sounds
result =>
{
returned = Microsoft.Xna.Framework.GamerServices.Guide.EndShowMessageBox(result);
mre.Set(); // Could have done it all without blocking
},null);
mre.WaitOne();
}
if (!returned.HasValue)
return MessagePromptResult.None;
else if (returned == 0)
return MessagePromptResult.Button1;
else if (returned == 1)
return MessagePromptResult.Button2;
else
return MessagePromptResult.None;
}
您需要将Microsoft.Xna.Framework.GamerServices的引用添加到您的项目中.
