Vb.net cannot change Datagridview column index

[GideonE]

I am trying to increase the width of a last dummy column in a datagridview so that I display certain rows after a button click.
The DGV is bigger that the screen so it scrolls, also the forth column is frozen.

I am using the following code :

Private Sub ButtonHierdieWeek_Click(sender As Object, e As EventArgs) Handles ButtonHierdieWeek.Click
        Dim BufferKolomWydte As Integer = 0
        For i As Integer = 23 To 32 Step 1
            SkeduleringDataGridView.Columns(i).Visible = False
            BufferKolomWydte = BufferKolomWydte + SkeduleringDataGridView.Columns(i).Width

        Next
        BufferKolomWydte = BufferKolomWydte + SkeduleringDataGridView.Columns(12).Width + SkeduleringDataGridView.Columns(13).Width


        SkeduleringDataGridView.FirstDisplayedScrollingColumnIndex = 15
        SkeduleringDataGridView.Columns(33).AutoSizeMode = DataGridViewAutoSizeColumnMode.NotSet
        SkeduleringDataGridView.Columns(33).Width = BufferKolomWydte

End Sub

However the column width does not change. I have set the DataGridViewAutoSizeColumnMode to NotSet above.
Is there another setting that I am missing?

Hi Gideon,

This might help.

You might like to note that

 For i As Integer = 23 To 32 Step 1

can be written as

 For i = 23 To 32

The index will always be an integer and the step is 1 by default so is only needed if the step is to be something other than 1, (-1, 2, 5 etc.)
