为什么不显示合计值？高手帮忙看看！谢谢！

直接在DataTable中加合计行，然后绑定到GridView

[快溜]

查询的时候就把合计查出来，或者在datatable里加一行合计

[暖枫无敌]

你的这个
else if (e.Row.RowType == DataControlRowType.Footer)
{
e.Row.Cells[3].Text = "合计：";
e.Row.Cells[4].Text = sum.ToString();
e.Row.Cells[5].Text = sum1.ToString();
}
判断在
if (e.Row.RowType == DataControlRowType.DataRow)
{
//上面的Footer添加的内容你放在了DataRow里，当然执行不到了。
}

你的那个RowDataBound的if...else 感觉太乱了，自己检查一下先。

以前帮别人写过类似的，你参考一下，原帖地址：
