我有一个showDialog。第一次加载showDialog后,我从viewModel调用另一个showDialog:
var connectionWindow = new ConnectionWindow();
connectionWindow.Closed += (o, args) =>
{
if (connectionWindow.DialogResult.HasValue && connectionWindow.DialogResult.Value)
{
}
else
{
}
};
connectionWindow.ShowDialog();
在第二个节目对话框中,我试图按照以下方式关闭它:
public ConnectionWindow()
{
_viewModel = new ConnectionWindowViewModel();
InitializeComponent();
DataContext = _viewModel;
_viewModel.ClosingRequest += () =>
{
DialogResult = true;
Close();
};
}
当closingRequest发生时,执行会在行
上中断DialogResult = true;
VS中没有错误或其他任何内容,但它没有关闭第二个showDialog窗口。关于如何关闭第二个对话框的任何想法?
修改 我想通过单击按钮关闭第二个showDialog。这是我的按钮的xaml代码:
<Button Content="Save Connection" Width="108" IsDefault="True" Command="{Binding OnSaveConnectionCommand}">
EDIT2 问题是从任务中解雇OnClosingRequest:
private void OnSaveConnection(object sender)
{
Mouse.OverrideCursor = Cursors.Wait;
var uiScheduler = TaskScheduler.FromCurrentSynchronizationContext();
Task.Factory.StartNew(() =>
{
if (IsServerConnected(_entityBuilder.ToString()))
{
OnClosingRequest();
}
else
{
MessageBox.Show("Cannot establish connection with server " , Properties.Resources.Error, MessageBoxButton.OK, MessageBoxImage.Error);
}
}).ContinueWith(_ => {Mouse.OverrideCursor = Cursors.Arrow;}, uiScheduler);
}
当我移动OnClosingRequest();一切都开始有效了。
