Gridview添加合计行问题！
--------------------编程问答-------------------- 直接在DataTable中加合计行，然后绑定到GridView --------------------编程问答-------------------- 查询的时候就把合计查出来，或者在datatable里加一行合计 --------------------编程问答-------------------- 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。 --------------------编程问答-------------------- 以前帮别人写过类似的，你参考一下，原帖地址：

--------------------编程问答-------------------- 好了，谢谢！
protected void GridView2_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
if ((e.Row.Cells[1].Text).Length > 16)
{
e.Row.Cells[1].Text = (e.Row.Cells[1].Text).Substring(0, 16) + "…";
}
if ((e.Row.Cells[2].Text).Length > 16)
{
e.Row.Cells[2].Text = (e.Row.Cells[2].Text).Substring(0, 16) + "…";
}
string id = e.Row.Cells[11].Text.ToString();
stockClass sc = new stockClass();
float not4 = sc.not(id);
if (not4 == 0)
{
e.Row.Cells[11].Text = "<font color=red>0</font>";
}
else
{
e.Row.Cells[11].Text = String.Format("{0:0.00}", not4);
}
string id2 = e.Row.Cells[10].Text.ToString();
stockClass sc2 = new stockClass();
float not5 = sc.not1(id);
if (not5 == 0)
{
e.Row.Cells[10].Text = "<font color=red>0</font>";
}
else
{
e.Row.Cells[10].Text = String.Format("{0:0.00}", not5);
}
}
else
{
if (e.Row.RowIndex >= 0)
{
sum += Convert.ToDouble(e.Row.Cells[4].Text);
sum1 += Convert.ToDouble(e.Row.Cells[5].Text);
}
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();
}
}
}
补充：.NET技术 , C#
