WPF, C# - Is it Possible to Set the ItemsSource of a Control in a Different Class From A Static Method?

Is it Possible to Set the ItemsSource of a Control in a Different Class From A Static Method?

I have an addin (class 1) that allows you to view and filter table records. Below the filters is a ListView control that displays saved queries and a button to open a window that manages those queries. In the window (class 2) you can add, edit, and delete queries. After the user saves changes, I would like to update the ListView control in class 1 from class 2. If possible I would like to use the following syntax:

//Class 1 Static Method:
public static void SetListViewItemsSource(ObservableCollection<Query> queries)
{
      this.listViewControl.ItemsSource = queries;
}

// To Change ItemsSource From Class2:
Class1.SetListViewItemsSource(queryCollection);

Open in new window

I know this approach is not possible because you cannot use the "this" keyword in a static method. Is there an alternative, WITHOUT having to create and instance of Class1??

Thanks!

This might be a dumb question...
How are you planning to see the control if you are not instantiating Class1?

As far as an approach goes, take a look at events. You could pass data via EventArgs when a query changes.

Class 1 is already instantiated because it is loaded first. The popup window loads from a button clicked on the Class 1. So, when an update to the user saves changes, in Class 2, I just want to copy the changes/collection to the ItemsSource in Class 1.

The event approach sounds promising, I am not positive how to implement it.

So, did the events approach work?
