Delegate control with class.cs

Question

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!

Answer 1

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.
