By the way, doing "% 4 != 0" is not the same as "> 3", but I'm guessing you know what you're doing there. =)

Well I hope so. ;) I do % 4 != 0 so every first 3 will always get the classextender set to " space" just every 4th one, which would result in the modulus being 0, gets the other class.

I changed the script to what you see below, but get an error message.

*slaps his forehead*

That was just stupid, that needed to be

classextender = "space";

Not

classextender == "space";

Let's just say it is early. But now this is fixed.

Oh, I rewrote it a tiny bit:

<div onClick="window.location.href='@c.Url';" class="@(string.Format("technieken{0}", classextender))"> 

See, I knew you knew what you were doing. :)

Oh actually, you also need to put a space in:

<div onClick="window.location.href='@c.Url';" class="technieken @classextender">

If that doesn't work, try to output @classextender elsewhere and see what happens. Maybe if it's empty your need to do @classextender.ToString()?

Ah, excellent, we're posting at the same time. No extra space needed then, as you really want to concat them. Great, glad it works!

What if I want the class attribute itself to by dynamic? For example in an li list only the last li needs the class="last". With xslt I could use xsl:attribute inside an if statement. How can I do that with razor? Can I just do this? 

classextender = "class=\"last\"";

You can do it with First() and Last() in 4,7.1. For now you can first count the results and do a for loop instead of a foreach loop. So when i == myCount you can add the "last" class. 

Hy Sebastiaan i know i'm posting terrible questions :) could you have a look at my post please ? Need some help for solving and integrating it into a customer project.
