How to fire the selected index changed event when combobox exists in a datagridview?

Hi experts
Using vb2008 express I have a datagridview with 3 colums, one is a comboboxcolumn and the other 2 are textbox columns, they are called cboAmount, txtPrice and txtTotalPrice, what i want to happen is when a number is selected in the combo-box it will be multiplied by the price and display the total price, if these controls were not in a datagridview I would simply use the selectedIndexChanged event of the combobox to do these calculations but what event can i use to do this when the combo-box exists in a datagridview?

Hope somebody can help.

How have you added the combobox to the datagridview?

Here's a small example how you can achieve that:
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim dgvCombo As DataGridViewComboBoxColumn = DirectCast(Me.Column3, DataGridViewComboBoxColumn)
        dgvCombo.Items.Add("one")
        dgvCombo.Items.Add("two")
        dgvCombo.Items.Add("three")    
    End Sub

    Private Sub DataGridView1_EditingControlShowing(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles DataGridView1.EditingControlShowing

        ' 2 = Column Index
        If Me.DataGridView1.CurrentCell.ColumnIndex = 2 Then
            Dim cb As ComboBox = DirectCast(e.Control, ComboBox)
            AddHandler cb.SelectedIndexChanged, AddressOf comboBox_SelectedIndexChanged
        End If

    End Sub

    Sub comboBox_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
        MessageBox.Show("ComboBox Changed!")
    End Sub
