Question : 'string' does not contain a definition for 'Controls' and no extension method 'Controls' accepting a first argument of type 'string' could be found

after converting my project in VS 2008, I get an error when trying to add the literal control PageTitle

Error    1    'string' does not contain a definition for 'Controls' and no extension method 'Controls' accepting a first argument of type 'string' could be found (are you missing a using directive or an assembly reference?)

Code Snippet:

1:	this.Title.Controls.Add(new LiteralControl(this.PageTitle));

Open in New Window

Select All

Answer : 'string' does not contain a definition for 'Controls' and no extension method 'Controls' accepting a first argument of type 'string' could be found

Is this a VS 2003 project that you are converting?

In framework 2.0 (VS 2005), the Title property was added to the Page class. I assume that you had an element in the page with the Id "Title"? If so, that control is not reachable by that name any more.

If you want to set the title of the page, use the Title property:

this.Title = this.PageTitle;

If you are using the element for something else, you have to assign a different Id to it so that you can reach it.
