You want an independent for loop for all the rows in grid view, then refer the below link

http://nikhilsreeni.wordpress.com/asp-net/checkbox/

Select all checkbox in Gridview

CheckBox cb = default(CheckBox);
for (int i = 0; i <= grdforumcomments.Rows.Count – 1; i++)
{
    cb = (CheckBox)grdforumcomments.Rows[i].Cells[0].FindControl(“cbSel”);

    cb.Checked = ((CheckBox)sender).Checked;
}

Select checked rows to a dataset; For gridview multiple edit

CheckBox cb = default(CheckBox);

foreach (GridViewRow row in grdforumcomments.Rows)
{
    cb = (CheckBox)row.FindControl("cbsel");
    if (cb.Checked)
    {
        drArticleCommentsUpdates = dtArticleCommentsUpdates.NewRow();
        drArticleCommentsUpdates["Id"] = dgItem.Cells[0].Text;
        drArticleCommentsUpdates["Date"] = System.DateTime.Now;dtArticleCommentsUpdates.Rows.Add(drArticleCommentsUpdates);
    }
}
