Question

我目前在使用Report Viewer控件时遇到问题。我当前的项目是一个MVC3应用程序，我在aspx页面中链接了Report Viewer控件。但是，页面显示，我根本无法翻阅结果。这是我的代码。

Report.aspx

Report Viewer

Answer 1

我明白了。我需要检查一下！IsPostBack在开头。每个PostBack只重新绑定数据并重置控件。应该知道这很简单。

Answer 2

不久前，我遇到了同样的问题。添加此简单的代码行以防止回发，您的分页问题将得到解决。

if (!IsPostBack){ //enter your report logic here }

分页不在报表查看器中工作
