Dispatcher.Invoke(new Action<System.Windows.DependencyProperty, object>(label.SetValue), System.Windows.Threading.DispatcherPriority.Background, new object[] { Label.ContentProperty, Convert.ToString((percent + 1)+"%") });
}
private event ProgressDelegate ProgressEvent;
private void beginImport()
{
Pro.Maximum = 100;
Pro.Value = 0;
label.Content = "0%";
ThreadPool.QueueUserWorkItem(state =>
{
Thread.Sleep(2000);
for (int i = 0; i < 100; i++)
{
if (ProgressEvent != null)
{
ProgressEvent(i);
}
Thread.Sleep(10);
}
});
}
}
