I have the following code and I am wondering what should be triggered in order for the DataGrid to show the two rows:

Dim loData As DataSet
loData = New DataSet("Customer")

Dim ordersTable As New DataTable("Temp")
loData.Tables.Add("Temp")

ordersTable.Columns.Add("OrderID", Type.GetType("System.Int32"))
ordersTable.Columns.Add("OrderQuantity", Type.GetType("System.Int32"))
ordersTable.Columns.Add("CustID", Type.GetType("System.Int32"))

ordersTable.PrimaryKey = New DataColumn() {ordersTable.Columns("OrderID")}

' Add two rows of data.
Dim dr As System.Data.DataRow

dr = ordersTable.NewRow()
dr("OrderID") = 1
dr("OrderQuantity") = 2
dr("CustID") = 3
ordersTable.Rows.Add(dr)

dr = ordersTable.NewRow()
dr("OrderID") = 4
dr("OrderQuantity") = 5
dr("CustID") = 6
ordersTable.Rows.Add(dr)

DataGrid.DataSource = loData
DataGrid.DataMember = "Temp"

Once the last two lines executed, I can see the DataGrid displaying some part of the grid but there is no data about the two rows I added.
