Problem Binding array of Processes to WPF ListBox?

I am wondering why you are getting an output at all ItemsSource="{Binding Path=ProcessName} Means the source of items is the ProcessName. The name is a string and a string is an IEnumerableIf you do this the binding of your list would change to ItemsSource="{Binding procList} However you should introduce a property and implement INotifyPropertyChanged so your UI is notified and updated when the datasource changes TL;DR version: taking a look at guides to XAML/Bindings and the MVVM Pattern is required if you want to take use full use of WPF.

I am wondering why you are getting an output at all. ItemsSource="{Binding Path=ProcessName}" Means the source of items is the ProcessName. The name is a string and a string is an IEnumerable.So the listbox displays each char as one entry.

You have to set the ItemsSource to the list itself. In your case it would be ItemsSource="{Binding}" Because the ProcessList is already the data context of your grid, which gets inherited to the listbox. If you are not using a view model class (which is best practice when working with the MVVM pattern) you can do a DataContext = this; in your windows constructor to set the data context of the window to its own code-behind.

Thanks for the reply. I'll look further into the MVVM pattern, have heard of it before but never studied it in detail. When I implement your change and have it as ItemsSource="{Binding}" the list populates but none of the entries have any text, any idea how I'd go about fixing this?

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
