Datagridview header center align: Why does my code keep getting changed?

Question

Hi all,

I'm doing this to center the header and data in column 3 and 4 of my datagridview control:

// 
// Column4
// 
this.Column4.DefaultCellStyle = dataGridViewCellStyle2;
this.Column4.HeaderText = "Qty (S2)";
this.Column4.Name = "Column4";
this.Column4.ReadOnly = true;
this.Column4.SortMode = System.Windows.Forms.DataGridViewColumnSortMode.NotSortable;
this.Column4.DefaultCellStyle.Alignment = System.Windows.Forms.DataGridViewContentAlignment.MiddleCenter;
this.Column4.HeaderCell.Style.Alignment = System.Windows.Forms.DataGridViewContentAlignment.MiddleCenter;

everytime I change a property (of any control) the block above gets changed to this:

// 
// Column4
// 
dataGridViewCellStyle2.Alignment = System.Windows.Forms.DataGridViewContentAlignment.MiddleCenter;
this.Column4.DefaultCellStyle = dataGridViewCellStyle2;
this.Column4.HeaderText = "Qty (S2)";
this.Column4.Name = "Column4";
this.Column4.ReadOnly = true;
this.Column4.SortMode = System.Windows.Forms.DataGridViewColumnSortMode.NotSortable;

The same things happens to column 3. I finally place the two lines below "InitializeComponent();". It looks like it is ok but why does my code kept getting modified?

Thanks.

To add: 

to allign 1st column you do:

dataGridView1.Columns[0].DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter; //cells alignment
dataGridView1.Columns[0].HeaderCell.Style.Alignment = DataGridViewContentAlignment.MiddleCenter; ///header alignment

...

but after InitializeComponent() method, otherwise you wlill get an error, becuase control has not been yet initialized!

Put the code bellow "InitializeComponent()" method.

Because this method creates all the controls in DGV!

After that, you do your own modifications.
