Question

Whats the best way to transfer data between the master page and the content page? I am accessing a rather large cache in the master page to display some information but the content page also needs to access the cache. So instead of loading the cache twice i thought it would be better to get the cache from the master page.

I created an interface witch i then use in my master page.

IMaster: myClass GetDataCache { get; } 
MasterPage: public partial class main : System.Web.UI.MasterPage, IMaster

Then i cast the master page inside my content page and retrieve the cache.

IMaster masterPage = (IMaster)Master;
myClass = masterPage.GetDataCache;

My question is, is this the best way to handle data between a master page and a content page?

Answer 1

Use the MasterType directive inside the ASPX page to get a strongly typed reference to the master page from within your content page (and from the code-behind of your content page).
