Question

I have an ASP.NET content page. The HTML tag associated with the content page is declared in the master page. I need to add an attribute to the HTML tag from the content page. My problem is, I do not know how to access this HTML tag from the content page.

Can someone please tell me how to do this?

Thank you

I wrote a routine this morning that helps me get a handle on master page controls recursively up the master page hierarchy (if you’re using nested master pages). I implemented it as an extension method. Perhaps you’ll find it useful:

public static TResult FindControlInMasterPages<TResult>(this MasterPage masterPage, string id)
    where TResult : Control
{
    return masterPage == null ? null :
           masterPage.FindControl(id) as TResult ?? FindControlInMasterPages<TResult>(masterPage.Master, id);
}

You could apply that like so:

this.Master.FindControlInMasterPages<Label>("myLabel").Attributes["attr"] = "value";
