SharePoint Stack Exchange is a question and answer site for SharePoint enthusiasts. It's 100% free, no registration required.

I searched on google for some clarifications but I didn't find the answers I've been looking for.

I want to deploy a delegate which would perform some custom functionality. That is why with a delegate I want to ship a classe with code, so I did a following:

I added a classe:

public class SomeClassForDelegate: WebControl
{
    protected override void Render(System.Web.UI.HtmlTextWriter writer)
    {
        writer.WriteLine("<p>Write some text</p>");
        base.Render(writer);
    }
}

Basically this classe will write just a text. The reason why I do that is just to test if my classe is being used, normally I'll add totaly difirent functionality.

Then I have a delegate declaration in element.xml:

<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
  <Control Id="AdditionalPageHead" ControlAssembly="$SharePoint.Project.AssemblyFullName$" ControlClass="mysolution.SomeClassForDelegate"  Sequence="90" />
</Elements>

Which I deploy with a feature.

Everything goes good and well but at the end I don't see the result.

What am I doing wrong?

Update: Solved

The problem was that the webcontrol was not put as safe control. So in an element.xml I added whole folder as a safe place. And it was working.

Thank you for input, especially Dribbel!

Are you just looking at the page, or at the page-source. The text will be inserted in the <head> element of the page and thus will not render in the browser. And Did you specify a Sequence value in your element file? –  Dribbel Aug 3 '12 at 6:15
    
Yep, I forgot the sequence and I added it. But still nothing :( –  Shkipper Aug 3 '12 at 6:31
    
Did you register it as safe control? Try adding a breakpoint, what does the ULS-log say? Check if it is correctly registered with this: blog.mastykarz.nl/… –  Dribbel Aug 3 '12 at 7:29
    
What Scope is the Feature? –  James Love Aug 3 '12 at 7:52
    
ok with the powershell script it seems it is ok it shows in controlclass for the additionialheaderpage: the src: mysolution.SomeClassForDelegate. But why it doenst do anything then? i even write some logs from Render or OnLoad methods but nothigs come in. –  Shkipper Aug 3 '12 at 8:00

Please check the following:

  • Is there any warning in the ULS-logs?
  • Is the sequence set correctly?
  • Does adding a breakpoint help (this checks if the code is actually loaded)
  • Check if the Control is referenced at all in the page using http://blog.mastykarz.nl/checking-which-delegate-controls-activated-site/ ?
  • Is the control registered as safe (check in the web.config after deploying)? Not safe controls will generate an error in the ULS-logs.
