ok - allow me to enter the sandbox and then get back to you.

main goal is:

1. never write the same markup twice. A list of MyObjects should always look the same, so no need to duplicate the markup.
2. being able to display same data twice without breaking goal number 1.

Actually its the exact same functionality that asp.net provides with user controls that im looking for ( Html.RenderPartial("mycontrol", somedata) )

You can use function forTemplate() on a DataObject to specify a template for the DataObject.

Another way is to add a custom methods to you DataObjects and use renderwith to assign a template to the view

function MyView(){
return $this->renderWith('MyViewTemplate');
}

In your template:

<% control MyDOSet %>
$MyView
<% end_control %>

Hi Martijn

Thank you so much for your reply! This was really helpful!
I actually managed to get another solution going, where I render the complete list of objects in one control and not the one object at a time. But this is only a matter of having the control-call in the include template or in the actual view.

Solution 1:

public function ControllerGetAll() {
$page = $this->customise(array(
'Pages' => $this->GetAllPages()
));

return $page->renderWith(array("PageList"));
}

PageList.ss
<% control Pages %>
$Title - ({$Link})
<% end_control %>

and used in the view like this:

$ControllerGetAll

But I actually like the other solution better - since its a bit cleaner.
Solution 2

Model describes a rendering for one object:
public function MyView(){
return $this->renderWith(array('PageRendering'));
}

in view:
<% control GetAllPages %>
$MyView
<% end_control %>

PageRendering.ss

$Title - ({$Link})

//the control-blocks are moved to the "main-view" instead of inside the included rendering

The cool thing about solution 1 is that it can be used as a REST-ful ajax-call-include since it will give you the complete list rendering on www.yourdom.com/controller/ControllerGetAll !!
