ASP.NET 2.0中的跨页发布 [英] cross page posting in ASP.NET 2.0

问题描述

大家好，

我有page1.aspx，单击此按钮时有一个按钮，我正在打开另一个page2.aspx
用户在其中选择一些asp:linkbutton，我必须将此信息发送回page1.aspx
并将执行进一步的逻辑

我正在使用跨页后退

1.使用page1.aspx作为上一页，并将page2.aspx作为源页面
2.单击保存页面2.aspx被打开，用户选择asp:linkbutton
3.页面被交叉发布回page1.aspx
但是这里的IsCrossPagePostBack总是错误的.


跨页过帐只是fwd吗?
建议一些解决方案

If you evaluate the IsCrossPagePostback like so:

if (this.Page.IsCrossPagePostback)

即使您确定它是正确的，您也总是会得到错误的信息.相反，您应该像这样检查属性:

you will always get false, even if you are sure that it should be true. Instead, you should check the property like this:

if (this.Page.PreviousPage != null &&
    this.Page.PreviousPage.IsCrossPagePostback)
