I am new to WPF and making it up as I go along so apologies if I have done anything drastically wrong.
I have a main window that makes a new 'error window' once particular user controls have completed their business. This new error window returns a 'loading placeholder' to UI whilst a background thread is updating another part of the 'error window'.
ErrorsWindow errorWindow = new ErrorsWindow();
errorWindow.LoadingPlaceholder.Text = string.Format(@"Loading...
Please wait {1} minutes and {0} seconds to see potential errors",
ConfigurationManager.AppSettings["ErrorWindowWaitSeconds"],
ConfigurationManager.AppSettings["ErrorWindowWaitMinutes"]);
errorWindow.Show();
this.Dispatcher.BeginInvoke((Action)(() =>
{
errorWindow.SetupWindow();
}), System.Windows.Threading.DispatcherPriority.Background);
So my errorWindow shows up in the UI with the loading placeholder text set correctly. The UI then waits 1 minute 30 seconds for the errorWindow.SetupWindow() method to complete. The issue is that during this wait period I cannot close the window until the errorWindow.SetupWindow() method has completed. Is there a way to allow the window to close and just abort the background thread?
EDIT: I cannot use a backgroundworker or a task as I need to update the UI elements inside the errorWindow.SetupWindow() method
Thankyou in anticipation
I found the answer to my question on another stackoverflow post here:
How to make some Tasks change my WPF controls
It involves doing the long running task on another thread(using System.Task) then using the dispatcher on the separate thread to affect the UI thread with any UI related changes.
