I just made a simple project demoing this if y'all would like to take a look (see attached .zip file).

But here's the basic setup (code omitted for brevity):

  Public Class Greeting
    Public Property Greeting As String
    Public Property Message As String
  End Class

  Public Property Messages As New BindingList(Of Greeting)

  UltraGrid1.DataSource = Messages

  Messages(0).Message = "Something else"

Obviously, the code isn't all in a row like this. They're in the appropriate methods. But the point is this: that last line is updating something in the grid's DataSource. I'd like that change reflected in the grid.

Unfortunately, in the actual project I'm working on, the only connection between where the data is set and where the grid resides is that list. Calling some sort of refresh on the grid isn't an option. It seems like simply updating the collection my grid is bound to should be enough. Is there something I'm missing? Thanks!
