Is this a Windows Forms DataGrid? If so, you can set the column width
to zero to hide a column provided you have a non-Nothing tablestyle.
Here is some code snippets.

'.... make sure your DataGrid is using a tablestyle
dataGrid1.DataSource = _dataSet.Tables("customers")
Dim dgts As New DataGridTableStyle()
dgts.MappingName = "customers"
dataGrid1.TableStyles.Add(dgts)

'......

'method to set a column with by colnumber
Public Sub SetColWidth(tableStyle As DataGridTableStyle, colNum As
Integer, width As Integer)
  Try
     tableStyle.GridColumnStyles(colNum).Width = width
     tableStyle.DataGrid.Refresh()
  Catch 'empty catch .. do nothing
  End Try
End Sub 'SetColWidth

'....

' here is how you might call this method
Private Sub button1_Click(sender As Object, e As System.EventArgs)
  Dim tableStyle As DataGridTableStyle =
dataGrid1.TableStyles("customers")
  SetColWidth(tableStyle, 1, 0) 'set width to zero
End Sub 'button1_Click
