Datagridview Multiple Row headers

[Xaphann]

Hi I have a DataGridView were I need to have multiple row headers. Like this;

          C1   C2   C3
Ra   R1
Ra   R2
Rb   R1
Rb   R1

Cannot seem to get it to work. Here is some sample test code I have been working with;

Public Class Form1


    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load




        Dim column0 As DataGridViewColumn = New DataGridViewTextBoxColumn()
        column0.DataPropertyName = "C0"
        column0.Name = " "
        DataGridView1.Columns.Add(column0)


        Dim column1 As DataGridViewColumn = New DataGridViewTextBoxColumn()
        column1.DataPropertyName = "C1"
        column1.Name = "C1"
        DataGridView1.Columns.Add(column1)


        Dim column2 As DataGridViewColumn = New DataGridViewTextBoxColumn()
        column2.DataPropertyName = "C2"
        column2.Name = "C2"
        DataGridView1.Columns.Add(column2)


  DataGridView1.RowHeadersWidth = CInt(DataGridView1.RowHeadersWidth * 1.25)
For x As Integer = 1 To 5
    DataGridView1.Rows.Add()
    DataGridView1.Rows(x - 1).HeaderCell.Value = "A" & x.ToString
    DataGridView1.Rows(x).HeaderCell.Value = "B" & x.ToString
Nextt


    End Sub
End Class

Thanks
