I have added a DataGridView to my form, set the form to maximize and Doc the DataGridview to fill, with the following code
Public Class Form1

  Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    Dim iRet As Integer
    DataGridView1.AlternatingRowsDefaultCellStyle.ForeColor = Color.Red
    DataGridView1.AlternatingRowsDefaultCellStyle.BackColor = Color.Wheat
    For i = 1 To 20
      DataGridView1.Columns.Add("Col" & i, "Col" & i)
    Next i
    For j = 1 To 100
      iRet = DataGridView1.Rows.Add()
      For x = 1 To 20
        DataGridView1.Rows(iRet).Cells(x - 1).Value = x * j
      Next x
  End Sub
End Class

My problem is, when I press the mouse button, hold it in and move my mouse over the screen in circle movements, it is very slow and flicker as the selection changed.

Is there any way to get past this?
