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

------解决方案--------------------
- C# code
for (int i = 0; i < GridView1.Rows.Count; i++)
{
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
}
}
