Olav,

The following is a snippet from the answer that Ken Cox gave on a similar
question. It should help you.

Dim dt As DataTable
Private Sub Page_Load _
(ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles MyBase.Load
DataGrid1.ShowHeader = True
DataGrid1.DataSource = CreateDataSource()
DataGrid1.DataBind()
End Sub
Private Sub DataGrid1_ItemDataBound _
(ByVal sender As Object, _
ByVal e As _
System.Web.UI.WebControls.DataGridItemEventArgs) _
Handles DataGrid1.ItemDataBound
' Have the first column header span
' two columns
' by Ken Cox Microsoft MVP [ASP.NET]
If e.Item.ItemType = ListItemType.Header Then
' Declare variables
Dim dgItem As DataGridItem
Dim tcells As TableCellCollection
Dim fcell As TableCell
Dim scell As TableCell
' Get a reference to the header row item
dgItem = e.Item
' Get a reference to the cells in the
' header row item
tcells = e.Item.Cells
' Get a reference to the cell we want to
' span. In this case, the first cell
fcell = e.Item.Cells(0)
' Set the text of the span cell
fcell.Text = "This is the spanned cell"
' Set the columns to span to 2
fcell.ColumnSpan = 2
' Get a reference to the second cell
scell = e.Item.Cells(1)
' Remove the second cell because it will
' be replaced by the spanning column
dgItem.Cells.Remove(scell)
End If
End Sub
Function CreateDataSource() As ICollection
' Create sample data for the DataList control.
dt = New DataTable
Dim dr As DataRow

' Define the columns of the table.
dt.Columns.Add(New DataColumn("Student", GetType(String)))
dt.Columns.Add(New DataColumn("Subject", GetType(String)))
dt.Columns.Add(New DataColumn("Day", GetType(String)))

' Populate the table with sample values.
dr = dt.NewRow
dr(0) = "Ben"
dr(1) = "English"
dr(2) = "Thursday"
dt.Rows.Add(dr)
dr = dt.NewRow
dr(0) = "Ben"
dr(1) = "Geology"
dr(2) = "Monday"
dt.Rows.Add(dr)
dr = dt.NewRow
dr(0) = "Ben"
dr(1) = "Physics"
dr(2) = "Tuesday"
dt.Rows.Add(dr)
Dim dv As DataView = New DataView(dt)
Return dv
End Function

<form id="Form1" method="post" runat="server">
<asp:DataGrid id="DataGrid1" runat="server"></asp:DataGrid>
</form>
