显示总计ListView中LayoutTemplate模板 [英] Displaying totals in the ListView LayoutTemplate

问题描述

我使用ListView控件（2008 ASP.NET）来显示一组数据线，并在底部我想有些合计。我最初将与当地一些功能，即＆LT定义在LayoutTemplate模板页眉和页脚，并获得总额;％＃GetTheSum（）％>，但现在看来，LayoutTemplate模板不处理的＆lt;％＃...... ％>语法。

I'm using the ListView control (ASP.NET 2008) to show a bunch of lines of data, and at the bottom I want some totals. I was initially going to define the header and footer in the LayoutTemplate and get the totals with some local function, i.e. <%#GetTheSum()%>, but it appears that the LayoutTemplate does not process the <%#...%> syntax.

另外一个想法是把一个标签在LayoutTemplate模板和使用的FindControl来更新它。不知道这是可能的（会尽量不久）。

Another thought would be to put a Label in the LayoutTemplate and use FindControl to update it. Not sure if that's possible (will try shortly).

什么是使用一个ListView显示总计的最佳方式？

What's the best way to show totals using a ListView?

推荐答案

原来，的FindControl不工作：

It turns out that FindControl does work:

CType(MyListView.FindControl("litTotal"), Literal).Text = GetTheSum()

我还是想知道，如果有可能，虽然一个更好的办法。

I'd still like to know if there might be a better way though.
