There is a small probability issue:
when in a child thread call the RadWindow.Alert method to show a message window
i use Application.Current.Dispatcher.BeginInvoke to call main thread
Application.Current.Dispatcher.BeginInvoke((Action)delegate
{
RadWindow.Alert(new DialogParameters { Header = StringResources.GetCodeMessage("TiShi"), Content = "error", Owner = Application.Current.MainWindow });
});
then there is a NullReferenceException occur
the exception stack is as following
在 Telerik.Windows.Controls.Primitives.TabStripPanel.<>c__DisplayClass14.<MeasureOverride>b__7(UIElement item)

I have no idea about this issue
Is any solution to avoid？

We've tried to reproduce the issue at our side but to no avail.
I suggest you open a support thread and attach your project so we can investigate further.

This issue is under A very small probability， It is difficult to appear again，
if the exception message is no help ，it seems there is no way to solve
If you manage to reproduce it in a sample project please write back with more details so we can investigate further.
