如何更改特定列的 Datagridview alignment 以进行打印？

Question

I apologize for my weird code. I'm a complete newbie and just learning how stuff works.

I found this code and changed some stuff to it.

My problem is:

I somehow managed for all columns the alignment to be right but I need for my first Colum "Data1" the alignment to be left. I can change that in the settings or with a click of a button but when printing it's just right aligned with the others.. I have tried everything but my knowledge is maybe 2% so I would really appreciate the help.

I have a Button1, DataGridView1, PrintPreviewDialog1, PrintDocument1, PrintDialog1

Here is a picture of the Form and an example of Print-Preview: https://drive.google.com/file/d/1VnUzrM9fgiEcJExrXalo7Uo6XKQwT3Sd/view?usp=sharing

This is my Code:

    Private mRow As Integer = 0
    Private newpage As Boolean = True
    Private m_PagesPrinted As Integer = 1

    Private Sub Form2_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        With DataGridView1
           .Rows.Add("Plan 1", "50", "2,99", "28,40", "170,90")
            .Rows.Add("Plan 27 a", "80", "14,99", "227,85", "1427,05")
            .Rows.Add("Plan 27 b", "808", "47,45", "84,85", "14,05")
            .Rows.Add("Plan 27 c", "80", "12,21", "77,10", "27,05")
            .Rows.Add("Plan 27 d", "470", "14,50", "15,40", "227,99")
            .Rows.Add("Plan 27 e", "2", "99,00", "2,84", "4427,67")
            .Rows.Add("Plan 27 f", "4", "10,00", "9,48", "7,74")
            .Rows.Add("Plan 27 g", "54", "150,50", "46,64", "127,50")
        End With
    End Sub

            PrintDocument1.Print()

Can somebody explain me what needs to be changed so when printing then the first column is left aligned and the rest is on the right side..

Thanks in advance!!

Your Select Case doesn't make sense. Your first Case matches DataGridViewContentAlignment.BottomRight twice and then your second case matches the same value twice more. In all cases, you're setting the Alignment of your StringFormat to StringAlignment.Far . I would think that it should be more like this:

Select Case DataGridView1.Columns(cell.ColumnIndex).DefaultCellStyle.Alignment
    Case DataGridViewContentAlignment.TopLeft,
         DataGridViewContentAlignment.MiddleLeft,
         DataGridViewContentAlignment.BottomLeft
        fmt.Alignment = StringAlignment.Near
    Case DataGridViewContentAlignment.TopCenter,
         DataGridViewContentAlignment.MiddleCenter,
         DataGridViewContentAlignment.BottomCenter
        fmt.Alignment = StringAlignment.Center
    Case DataGridViewContentAlignment.TopRight,
         DataGridViewContentAlignment.MiddleRight,
         DataGridViewContentAlignment.BottomRight
        fmt.Alignment = StringAlignment.Far
