Question

I have a public method in my content page class, I want to call this method from master page class.

Answer 1

You can inherit your page from a base class. Then you can create a virtual method in your base class which will get overridden in your page. You can then call that virtual method from the master page like this –

(cphPage.Page as PageBase).YourMethod();

Here, cphPage is the ID of the ContentPlaceHolder in your master page. PageBase is the base class containing the YourMethod method.

EDIT: Of course, you’ll have to put a null checking before you call the YourMethod method using the page’s instance.
