		Hi ?,

vielleicht geht's so:

Public Class Form4
    Inherits System.Windows.Forms.Form
    Private WithEvents m_theTable As New DataTable
    Private WithEvents m_dc1 As DataColumn
    Private WithEvents m_dc2 As DataColumn
    Private WithEvents m_dc3 As DataColumn
#Region " Vom Windows Form Designer generierter Code "

    Public Sub New()
        MyBase.New()
        InitializeComponent()
    End Sub

    Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
        If disposing Then
            If Not (components Is Nothing) Then
                components.Dispose()
            End If
        End If
        MyBase.Dispose(disposing)
    End Sub

    Private components As System.ComponentModel.IContainer
    Friend WithEvents DataGrid1 As System.Windows.Forms.DataGrid
    <System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()
        Me.DataGrid1 = New System.Windows.Forms.DataGrid
        CType(Me.DataGrid1, System.ComponentModel.ISupportInitialize).BeginInit()
        Me.SuspendLayout()
        '
        'DataGrid1
        '
        Me.DataGrid1.DataMember = ""
        Me.DataGrid1.HeaderForeColor = System.Drawing.SystemColors.ControlText
        Me.DataGrid1.Location = New System.Drawing.Point(16, 24)
        Me.DataGrid1.Name = "DataGrid1"
        Me.DataGrid1.Size = New System.Drawing.Size(656, 240)
        Me.DataGrid1.TabIndex = 0
        '
        'Form4
        '
        Me.AutoScaleBaseSize = New System.Drawing.Size(5, 13)
        Me.ClientSize = New System.Drawing.Size(704, 628)
        Me.Controls.Add(Me.DataGrid1)
        Me.Name = "Form4"
        Me.Text = "Form4"
        CType(Me.DataGrid1, System.ComponentModel.ISupportInitialize).EndInit()
        Me.ResumeLayout(False)

    End Sub

#End Region

    Private Sub Form4_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Me.MakeTheTable()
        Me.DataGrid1.DataSource = Me.m_theTable
    End Sub

    Private Sub MakeTheTable()
        Me.m_dc1 = New DataColumn("Col1", GetType(String))
        Me.m_dc1.DefaultValue = "TEXT"
        Me.m_dc2 = New DataColumn("Col2", GetType(String))
        Me.m_dc2.DefaultValue = "TEXT"
        Me.m_dc3 = New DataColumn("Col3", GetType(String))
        Me.m_dc3.DefaultValue = "TEXT"
        Me.m_theTable.Columns.Add(Me.m_dc1)
        Me.m_theTable.Columns.Add(Me.m_dc2)
        Me.m_theTable.Columns.Add(Me.m_dc3)
    End Sub

    Private Sub m_theTable_ColumnChanged(ByVal sender As Object, ByVal e As System.Data.DataColumnChangeEventArgs) Handles m_theTable.ColumnChanged
        e.Row("Col2") = "geändert"
    End Sub
End Class
