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.
