WebForm AddHeader implemented?

[crevilla]

Hello,

Has anyone tried to work with WebForms and the AddHeader function. According to help, it accepts an string as argument. However, when I test the app the header is not included.

Code snippet:

Webform1.AddHeader("<link href=\"http://cdn.syncfusion.com/19.4.0.38/js/ ... ll.min.css\" rel=\"stylesheet\" />")

Any ideas?

UPDATE: Or how can I add an external javascript library to my header (or project)? Any help will be appreciated.

Thanks
