问题描述
嗨。
我在主页之间有一些情况沟通..
这是我的情景
我有一个主人页面（顶部）名为MainMasterPage，其中有一个按钮和一个文本框。
然后是名为CategoryMasterPage的第二个母版页，它是主要的子项。
然后有一个页面SearchResults.aspx，其中有一个转发器控件。
现在我想要的是当我点击按钮（它在mainMasterPage），它应该在searchResults.aspx中触发它的事件而不是它自己的主页的cs文件。
这样我就可以访问searchResults.aspx的控件来轻松附加数据。
换句话说，当点击按钮时，我想在searchResults页面中显示文本框数据。
我也按照这个链接 []
但它仅在与一个主人和一个孩子一起工作时有效。我因嵌套母版页而遇到问题..
谢谢。
Hi.
I have a bit of Situation communicating in between Master Pages..
Here is my Scenario
I have a Master Page(Top) named "MainMasterPage" which have a button and a text box in it.
Then a Second Master Page named "CategoryMasterPage" which is Child of the main.
Then there is a page "SearchResults.aspx" which have a repeater control in it.
now all I want is that when i click the button (which is in mainMasterPage), it should trigger its event in searchResults.aspx instead of the cs file of it own masterpage.
so that i can access searchResults.aspx's control to append data easily.
in other words I want text box data in searchResults page when the button is clicked.
I've followed this link too Master Page, Child Pages: Dynamic Communication Flexibility[^]
but its only valid while working with one master and one child. I am having problem due to nested master pages..
Thanks.
