DataGrid and Class Collections

[WoundEdGoat]

Right, well I've been searching around the net for about half a day now and to be quite honest, I'm under the impression that my conception of how to use a DataGrid control is horribly flawed (or non-existent).

What I would like to do is pass the data in a Collection (containing objects from a class I wrote) to a DataGrid control so that it can be easily viewed and possibly sorted.

I've got it to display the data with the DataGrid.DataSource = Collection line, but it displays the data columns in an order I've not yet figured out how it came by. After doing some more research on the net, I learned of the TableStyles and GridColumnStyles collections. Well, I tried to implement these into my code, both using the properties window and via code, but they don't seem to work, leading me to believe that I haven't a clue to what I'm doing.

I suppose what I'm here to ask is for some direction as to what I'm suppose to do to get this thing to work properly. I'll post a cut down version of my code below.

My Class (Basically):

Public Class DataClass
	Private strString as String
	Private intNumber as Integer

	Public Property StringProp() As String
		Get
			Return strString
		End Get
		Set(ByVal Value As String)
			strString = Value
		End Set
	End Property

	Public Property NumberProp() As Integer
		Get
			Return intNumber
		End Get
		Set(ByVal Value As Integer)
			intNumber = Value
		End Set
	End Property

	Public Sub New()
		' Code
	End Sub
End Class

And the TableStyles and GridColumnStyles code (which I copied off a website and modified to fit my program... Or at least that was the idea), which is in my Form.Load event currently:

	Dim dgtsTable As New DataGridTableStyle()
	dgtsTable.MappingName = "DataClass” ' Not sure if this is correct...

	Dim dgtbString As New DataGridTextBoxColumn()
	dgtbString.HeaderText = "String Value"
	dgtbString.MappingName = "StringProp" ' Or if this is correct...
	dgtbString.Width = "165"
	dgtsTable.GridColumnStyles.Add(dgtbString)

	Dim dgtbNumber As New DataGridTextBoxColumn()
	dgtbNumber.HeaderText = "Number Value"
	dgtbNumber.MappingName = "NumberProp" ' Or this...
	dgtbNumber.Width = "180"
	dgtsTable.GridColumnStyles.Add(dgtbNumber)

	dgdDataGrid.TableStyles.Clear()
	dgdDataGrid.TableStyles.Add(dgtsTable)

After this, I'm stumped. It didn't make a difference if I put the DataGrid.DataSource = Collection either before or after the latter block of code. Any help would be greatly appreciated. Thanks.
