前台:
后台:
private int num = 0;
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
DataRowView dr = e.Row.DataItem as DataRowView;
num += Convert.ToInt32(dr.Row["first"]);
}
else if (e.Row.RowType == DataControlRowType.Footer)
{
Label LabelAll = e.Row.FindControl("labelAll") as Label;
if (LabelAll != null)
{
LabelAll.Text += num.ToString();//"计算的总数,或者也可以单独计算";//
}
}
}
"first"是数据源的一个字段
