我想要的效果是 列1 列2 列3 总计
行1
行2
行3foreach (GridViewRow gvr in GridView1.Rows)
{
foreach (TableCell gvCell in gvr.Cells)
{
}
}
如何用遍历的方法计算gridview每行的总计？

{
for (int j = 0; j < GridView1.Columns.Count; j++)
{
GridView1.Rows[i].Cells[3].Text = 列1+列2+列3;//最好转化后相加
}
}
//如果总计ID为lump,JS遍历不知道可以吗
});for(int i=0;i<gridview1.rows.count;i++)
{
//如果总计的标签是lbl1
Label lbl = gridview.findcontrol["lbl1"] as Label;
//接下来
}
