Asssuming that you are using BoundFields for the first three columns and you want to handle the LinkButton-click event (instead of the e.g. RowCommand of the GridView):

protected void CloseLinkClicked(Object sender, EventArgs e)
{
    var closeLink = (Control) sender;
    GridViewRow row = (GridViewRow) closeLink.NamingContainer;
    string firstCellText = row.Cells[0].Text; // here we are
}

If you are using TemplateFields and the value aa is in a Label (e.g. LblValue):

Label lblValue = (Label) row.FindControl("LblValue"); // lblValue.Text = "aa"
