我在 Windows Phone 8 上工作，我遇到了在消息框中询问用户的情况，因此用户必须单击"is"或“否”。
但是消息框只有确定和取消按钮，我不需要它。
这是我的代码:
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);
}
我如何将其修改为是和否按钮？我还可以有 3 个按钮以及按钮上的自定义文本吗？
请您参考如下方法:
您可以使用这个自定义消息框

你可以调用这个消息框
对于是否按钮
SLMessageBox messBox;
messBox = new SLMessageBox("Message", "Yes or No Message Box...!", SLMessageBox.MessageBoxButtons.YesNo, SLMessageBox.MessageBoxIcon.Information);
messBox.Show();
仅用于确定按钮
SLMessageBox messBox;
messBox = new SLMessageBox("Message", "Ok Message Box...!", SLMessageBox.MessageBoxButtons.Ok, SLMessageBox.MessageBoxIcon.Information);
messBox.Show();
对于确定和取消按钮
SLMessageBox messBox;
messBox = new SLMessageBox("Message", "Ok and Cancel Message Box...!", SLMessageBox.MessageBoxButtons.OkCancel, SLMessageBox.MessageBoxIcon.Information);
messBox.Show();
编辑: 并检查用户点击的 MessageBox 的结果
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
{
//...
}
}
