ma secondo voi così deve funzionare?

codice:
Public Class Form1
    Inherits System.Windows.Forms.Form

    Dim ts1 As New System.Windows.Forms.DataGridTableStyle
    Dim ts2 As New System.Windows.Forms.DataGridTableStyle
    Dim ts3 As New System.Windows.Forms.DataGridTableStyle
    Dim ts4 As New System.Windows.Forms.DataGridTableStyle
    Dim ts5 As New System.Windows.Forms.DataGridTableStyle
codice:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        Dim c0 As New DataGridTextBoxColumn
        Dim c1 As New DataGridTextBoxColumn
        Dim c2 As New DataGridTextBoxColumn
        Dim c3 As New DataGridTextBoxColumn
        Dim c4 As New DataGridTextBoxColumn

        c0.Width = "95"
        c1.Width = "50"
        c2.Width = "20"
        c3.Width = "60"
        c4.Width = "80"

        ts1.GridColumnStyles.Add(c0)
        ts2.GridColumnStyles.Add(c1)
        ts3.GridColumnStyles.Add(c2)
        ts4.GridColumnStyles.Add(c3)
        ts5.GridColumnStyles.Add(c4)

        DataGrid1.TableStyles.Add(ts1)
        DataGrid1.TableStyles.Add(ts2)
        DataGrid1.TableStyles.Add(ts3)
        DataGrid1.TableStyles.Add(ts4)
        DataGrid1.TableStyles.Add(ts5)
