Question

I have a main window, which is the application start up window.
In that window, there is a Repeater control binded to a SQL Database, and a button to open a new window.

The new window has a method that inserts data into the SQL Database that the first windows’ Repeater control reads from.

The repeater has a RepeaterRefresh() method that forces it to rebind to the SQL Database, revealing anything added.

How would I be able to bind the Close() event of the second window to the RepeaterRefresh() method, so the data is automatically shown on the repeater.

I have read this, this and this, but I still feel that my question doesn’t relate.

Answer 1

Why not simply add a handler to the Closing or Closed event:

private void ShowChildWindow()
{
    Window childWindow = new ChildWindow();
    childWindow.Closed += ChildWindowClosed;
    childWindow.Show();
}

private void ChildWindowClosed(object sender, EventArgs e)
{
    ((Window)sender).Closed -= ChildWindowClosed;
    RepeaterRefresh();
}
