                items.Append(string.Format("{0},", item.Value));

            {
                item.Selected = items.Where(c => c.Equals(item.Value))
                    .FirstOrDefault() != null;

Try this:

C#

private string populateselecteditems(string selecteditems, CheckBoxList CheckBoxList1)
    {
        if (!string.IsNullOrWhiteSpace(selecteditems))
        {
            string[] items = selecteditems.Split(',');
            foreach (ListItem item in CheckBoxList1.Items)
            {
                item.Selected = items.Where(c => c.Equals(item.Value))
                    .FirstOrDefault() != null;
            }
        }
        return selecteditems;


    }

C#

protected void Button1_Click(object sender, EventArgs e)
    {
            // Textbox1.Text = populated values should be here.
        //Textbox1.Text = populateselecteditems(selecteditems ,CheckBoxList CheckBoxList1);

       Textbox1.Text=populateselecteditems(selecteditems ,CheckBoxList CheckBoxList1);
}
