Adding multiple controls to AdditionalPageHead

Question

My question is regarding the delegate control AdditionalPageHead, as we know it allows multple controls to be loaded.

My questions are:

• How to add multiple controls?
• I want that the different controls are activated by different future.

Example: I have first.ascx which is deployed with site scoped feature1 and i have a second.ascx which is deployed with site scope feature2.

Is it possible so that the second.ascx is added to the first.ascx or the other way around?

Answer 1

In feature 1 have an elements.xml with:

<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">  
  <Control Id="AdditionalPageHead" 
           Sequence="90"             
           ControlSrc="~/_CONTROLTEMPLATES/XXX/first.ascx" />
</Elements>

In feature 2 have an elements.xml with:

<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">  
  <Control Id="AdditionalPageHead" 
           Sequence="91"             
           ControlSrc="~/_CONTROLTEMPLATES/YYY/second.ascx" />
</Elements>

Sequence controls the order
