Function CreateDataSource() As ICollection

Dim dt As New DataTable()

Dim dr As DataRow

dt.Columns.Add(New DataColumn("IntegerValue", GetType(Int32)))

dt.Columns.Add(New DataColumn("StringValue", GetType(String)))

dt.Columns.Add(New DataColumn("CurrencyValue", GetType(Double)))

Dim i As Integer

For i = 0 To 8

dr = dt.NewRow()

dr(0) = i

dr(1) = "Item " + i.ToString()

dr(2) = 1.23 *(i + 1)

dt.Rows.Add(dr)

Next i

Dim dv As New DataView(dt)

Return dv

End Function 'CreateDataSource

Sub Page_Load(sender As Object, e As EventArgs)

If Not IsPostBack Then

' Load this data only once.

ItemsGrid.DataSource = CreateDataSource()

ItemsGrid.DataBind()

End If

End Sub 'Page_Load
