我创建了一个水晶报表并附加到aspx页面上的一个按钮。但是按钮后面的代码根本不会被调用。请帮忙。aspx页面后面的代码没有被触发
axpx页面代码：
后面的页面<%@ Page Title="Department Average Competency Rating" Language="vb" AutoEventWireup="false" MasterPageFile="~/PageTemplate.master"

是的，处理程序的代码位于代码后面......但您必须将其连接到UI中，以便在单击该按钮时调用它。只需将OnClick属性添加到按钮：http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.button.onclick(v=vs.110).aspx显示添加按钮点击处理程序在.aspx页面和后面的代码中（尽管只需要一个）。 – Patrick
