带有“是”和“否”按钮的消息框
本文关键字：消息 按钮 带有 | 更新日期: 2023-09-27 17:51:05
我在Windows Phone 8上工作，我有在消息框中询问用户的场景，所以用户必须点击是或否。
但是消息框只有OK和Cancel按钮，我不需要它。
下面是我的代码:MessageBoxResult m = MessageBox.Show("Are you sure? This will delete all your data", "Attention!", MessageBoxButton.OKCancel);
if (m == MessageBoxResult.Cancel)
{
}
else
{
MessageBox.Show("Data Deleted", "Done", MessageBoxButton.OK);
}
我如何将此修改为YES和NO按钮?还有，我能不能有3个按钮，按钮上有自定义文本?
您可以使用此自定义消息框

你可以把这个叫做Message Box
For Yes No Buttons
SLMessageBox messBox;
messBox = new SLMessageBox("Message", "Yes or No Message Box...!", SLMessageBox.MessageBoxButtons.YesNo, SLMessageBox.MessageBoxIcon.Information);
messBox.Show();
For Only For Ok Button
SLMessageBox messBox;
messBox = new SLMessageBox("Message", "Ok Message Box...!", SLMessageBox.MessageBoxButtons.Ok, SLMessageBox.MessageBoxIcon.Information);
messBox.Show();
Ok和Cancel按钮
SLMessageBox messBox;
messBox = new SLMessageBox("Message", "Ok and Cancel Message Box...!", SLMessageBox.MessageBoxButtons.OkCancel, SLMessageBox.MessageBoxIcon.Information);
messBox.Show();
编辑:为了检查MessageBox的结果用户点击了什么
SLMessageBox messBox;
messBox = new SLMessageBox("Message", "Yes, No and Cancel Buttons Message Box...!", SLMessageBox.MessageBoxButtons.YesNoCancel, , SLMessageBox.MessageBoxIcon.Information);
messBox.Show();
messBox.OnMessageBoxClosed += messBox_OnDeleteMessageBoxClosed;
private void messBox_OnDeleteMessageBoxClosed(MessageBoxResult result)
{
if(result==MessageBoxResult.Yes)
{
//....
}
else if(result==MessageBoxResult.No)
{
//....
}
else
{
//...
}
}
API只公开OK/Cancel。你可以使用Coding4FunToolkit中的Coding4Fun MessagePrompt来创建Yes/No消息:
MessagePrompt msgPrompt = new MessagePrompt();
msgPrompt.Message = "Your Message.";
Button yesBtn = new Button() { Content = "Yes" };
yesBtn.Click += new RoutedEventHandler(yesBtn_Click);
Button noBtn = new Button() { Content = "No" };
noBtn.Click += new RoutedEventHandler(noBtn_Click);
msgPrompt.ActionPopUpButtons.Add(noBtn);
msgPrompt.ActionPopUpButtons.Add(yesBtn);
msgPrompt.Show();
API只公开"OK"answers"Cancel"。如果你需要使用不同的按钮，恐怕你必须使用自定义消息框。

http://blogs.microsoft.co.il/tomershamam/2010/10/19/windows-phone-7-custom-message-box/不，MessageBox是一个密封类型。
您需要创建自己的MessageBox控件，该控件具有"Yes"answers"No"按钮。
另一个选择是使用来自XNA框架的Guide类。有一个BeginShowMessageBox方法，它给了你传递任何你想要的字符串给按钮的选项。
