When I do the following, not all of my bindings and UI content is updated correctly. What is the problem?
privatevoid DoWorkCommandExecuted() { //Do stuff ShowProgress = Visibility.Visible; Task.Factory.StartNew(() => { //Thread.Sleep(3000);for (int i = 0; i < 10000; i++) { s += i.ToString(); } ObservableCollection<string> temp = newObservableCollection<string>(); temp.Add("One"); temp.Add("Two"); temp.Add("Three"); temp.Add("Four"); temp.Add("Five"); BillingCycles = temp; SelectedBillingCycle = BillingCycles[0]; }) .ContinueWith(t => { ShowProgress = Visibility.Hidden; }); }
I have some properties like this that are bound to buttons, and the buttons should become disabled or enabled based on these properties but do not after running the above code:
private bool CanFirst { get { bool b = false; if (BillingCycles != null) { if (BillingCycles.Count > 0 && SelectedBillingCycle != BillingCycles[BillingCycles.Count - 1]) { b = true; } } return b; } }Yes, I am using INotifyPropertyChanged. When I do not use the Task.Factory.StartNew code, the buttons are properly enabled/disabled, but i need to use it so the ProgressBar is acutally shown when process is happening, then hidden when done.
