How to add checkbox in Asp.net Gridview in all header columns

Question

I am new in asp.net developer.

Populated a asp.net grid view with the help of data table and my all columns are dynamic. Now i want to add a check box in my all columns dynamically bot do not want to add in rows. One time i can check only one check box.If i am selecting second time check box in that case first selected check box should be unchecked.

My code is below:

protected void dgvWoList_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.Header)
        {
            for (int i = 0; i < e.Row.Cells.Count; i++)
            {
                if (e.Row.Cells[i] != null && (!e.Row.Cells[i].IsNullOrEmpty()))
                {
                    CheckBox chk = new CheckBox();
                    chk.Text = e.Row.Cells[i].Text;
                    e.Row.Cells[i].Controls.Add(chk);

                }
            }
        }
    }

Now i am trying to uncheck the check box but unable to do. Plz help me.

Answers: Thanks a lot for your responses. Spl thanks AnthonyBCodes for your advise instead of check box use radio button which solved my problem. I changed my code from check box to radio button as below.

                        RadioButton chk = new RadioButton();
                        chk.GroupName = "radio";
                        chk.Text = e.Row.Cells[i].Text;
                        e.Row.Cells[i].Controls.Add(chk);
