I work on an application which has a main window and some TextBlocks on it. Once user clicks a TextBlock, a new window is created and display the data chart related to that TextBlock. I create such new chart Wndow on a different thread, as following:
private void xTB_MouseDown(object sender, MouseButtonEventArgs e) { Thread _displayChartThread = new Thread(() => { Window w = new Window() w.Closed += (sender2, e2) =>w.Dispatcher.InvokeShutdown(); w.Show(); System.Windows.Threading.Dispatcher.Run(); }); _displayChartThread.SetApartmentState(ApartmentState.STA); _displayChartThread.IsBackground = true; _displayChartThread.Start(); } The problem is, when you have multiple chart windows open, and you close the main window, the chart windows are still open and not get destroyed. I can see that the chart windows have no knowledge of the main window being their Owner, and I can't set their Owner property to main window in the thread in which chart window is created.
Any ideas on how to handle this? I mean once main window is closed, all the chart window (created in different threads) are also closed.
Thanks in advance.
