totalunbalanced += Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, "unbalanced"));
totalsettled += Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, "settled"));
}
else if(e.Row .RowType ==DataControlRowType .Footer )
{
e.Row.Cells[0].Text = "合计";
e.Row.Cells[1].Text = totalcash.ToString("0.00");
e.Row.Cells[2].Text = totalunbalanced.ToString("0.00");
e.Row.Cells[3].Text = totalsettled.ToString("0.00");
