C# .NET - CHECKBOX column in DATagridiview

Hi, can some on help me with my problem?

How can I add a checkbox column programmatically and making it as a first column.

here is my code, but the checkbox is at the last column.

private void Form1_Load(object sender, EventArgs e)
    {
      string stat = "";
      int ave = 0;
      dataGridView1.ColumnCount = 5;


      DataGridViewCheckBoxColumn chk = new DataGridViewCheckBoxColumn();
      dataGridView1.Columns.Add(chk);
      chk.HeaderText = "Check Data";
      chk.Name = "chk";

      dataGridView1.Columns[1].Name = "Substation/Office";
      dataGridView1.Columns[2].Name = "IP Address";
      dataGridView1.Columns[3].Name = "Status";
      dataGridView1.Columns[4].Name = "Average";

      string[] row = new string[] { "ce", "1", stat};
      dataGridView1.Rows.Add(row);
      row = new string[] { " Da", "1.1", stat };
      dataGridView1.Rows.Add(row);
      row = new string[] { "s", "19", stat };
      dataGridView1.Rows.Add(row);
      row = new string[] { "cat", "1", stat };
      dataGridView1.Rows.Add(row);
      row = new string[] { "te", "6.1", stat };
      dataGridView1.Rows.Add(row);
      row = new string[] { "ffice", ".1", stat };
      dataGridView1.Rows.Add(row);
      row = new string[] { "ca", "51.1", stat };
      dataGridView1.Rows.Add(row);
      row = new string[] { "ban", "1", stat };
      dataGridView1.Rows.Add(row);
      row = new string[] { "Office", "1", stat };
      dataGridView1.Rows.Add(row);
      row = new string[] { "or", "19", stat };
      dataGridView1.Rows.Add(row);
      row = new string[] { "Sur", "19", stat };
      dataGridView1.Rows.Add(row);
      row = new string[] { "C", "3.1", stat };
      dataGridView1.Rows.Add(row);
      row = new string[] { "Norte", "1", stat };
      dataGridView1.Rows.Add(row);
      row = new string[] { "Sto", "10", stat };
      dataGridView1.Rows.Add(row);
      row = new string[] { "mail", "1", stat };
      dataGridView1.Rows.Add(row);
    }



the checkbox column always appear at the last column of the grid view.
ANd this is the scenario:

you will get some guide from this link'

didn't you get answer from below post that you have posted ?

http://www.eggheadcafe.com/community/aspnet/2/10227035/data-grid-view-with-checkbox-column.aspx

did you try by below ?

dataGridView1.Columns[0].Name = "chk"; // header name

okay that helped...that added another column that appears on the first grid,

but my problem as that i have errors when i'm trying to insert values for the other textbox columns,
 the values are always placed at the first column (w/c is the checkbox column) and its not supposed to happen..can you help me with that? thanks

obviously it will gives you the error. The reason is that in your stirng array you are just storing 3 values so it will alwayz add value to 0, 1 and 2 cells. So your first column or column on 0 location is Checkbox type so it will gives error..

so do something like that :

 string[] row = new string[] { "true", "ce", "1", stat};
 dataGridView1.Rows.Add(row);
 row = new string[] { "false" ,"Da", "1.1", stat };
dataGridView1.Rows.Add(row);

try by it ..

You should move the statement dataGridView1.ColumnCount = 5; further down,
