		' connecting up your own data source should be relatively straightforward.
		' Just connect, get the data, and databind to the grid and you should be good.

		Dim myRow     As DataRow

		myTable.Columns.Add("ID", Type.GetType("System.Int32"))
		myTable.Columns.Add("Title", Type.GetType("System.String"))
		myTable.Columns.Add("Description", Type.GetType("System.String"))
		' Fill it with sample data:
		For iLetter = Asc("A") To Asc("M")
			myRow = myTable.NewRow()
			myRow("ID")          = iLetter - 64
			myRow("Title")       = "The Letter " & Chr(iLetter)

		' Notice the formatting is handled completely by the grid itself.
		' This is nice because this way when you want to change the look
		' of the grid you don't need to worry about messing with your DB
		' code.  You can just change the attributes of the datagrid and
		' you never have to get anywhere near anything else.
