    e.Cancel = Not IsNumeric(DataGridView1.Item(e.ColumnIndex, e.RowIndex)) 
End Sub 

Private Sub DataGridView1_DataBindingComplete(sender As Object, e As DataGridViewBindingCompleteEventArgs) _ 
Handles DataGridView1.DataBindingComplete 
    For Each col As DataGridViewColumn In DataGridView1.Columns 
     Select Case col.DataPropertyName 
      Case "Col1" ' from Table or Linq 
       col.HeaderText = "My Column 1" 
      Case "Col2" ' from Table or Linq
