    Using functions in macro parameters

    I need to pass a url of a content item to a .net control.

    My not-working solution:
    * create control with public property
    * create macro with parameter (url, string)
    * create document type
    * add content picker to document type (urlID)
    * create template
    * add macro to template
    * give urlID to macro parameter

    now the problem is the urlID should be parsed to the url using umbraco.library:NiceUrl()

    Not-working code:

    Is it possible to convert the urlID in the template?
    I know I could do it in the code of the control as well, but I need an other way now.

    Can a library function be used inside a template like I try to do?

    You CAN use simple library calls in a template using the xslt feature of the umbraco:Item tag.

    Here's how to do it...

    First, we'll just display the id to be sure it is being picked up properly. Then we'll add a bit of inline xslt to give us the nice url. To do this, put the following in your template (assuming the urlID is the docType property):

    The easy way to do this is to use the button on the toolbar when you're editing a template. Then you just select the field and you've got the umbraco:Item tag.

    When you view your website you should see the id displayed.

    Once you've got the id, we'll just add a bit of inline xslt (see this umbraco book for more details: [url][/url])


    Basically, it applies the xslt command and uses whatever is in the field="" and puts it into the xslt at the {0} placeholder.

    Hope that helps.

    First of all a big thanks. I got it to work this far.

    The second and final problem I now have is that I need to insert this formatted item value in the macro of my user control.


    Generates the correct output and should now be linked to the url parameter of the macro.


    Once again thanks for the help so far. Greetings

    Was this ever figured out? I'm having the same trouble trying to insert a URL (from Content Picker ID) into a Macro property.

    Same issue here (i posted my thread here: passing a mediaitemurl to a macro as parameter (in a masterpage) - UI Questions - ) is there a solution at hand?

    I was able to do something like this using:

    <umbraco:Macro Alias="SomeAlias" runat="server" PassValue="[#ValueInContentManager]"></umbraco:Macro>

    I think the problem above might have been


    Notice "#urlID" doesn't have a closing bracket "]" though I'm not sure if that's it because I wasn't doing exactly the same thing.
