What type is fieldset? Have you tried something like the following, assuming your fieldset is of type IPublishedContent? 

@{
    var id = fieldset.GetPropertyValue<int>("slideLink");
    var url = Umbraco.NiceUrl(id);
}

Archetype?

   @{ 
        var myLink = fieldset.GetValue<int>("slideLink");
    }
    <a href="@Umbraco.NiceUrl(myLink)">Click</a>

Yup tried that, you cant <int>, it returns an errror.

.fieldset is an archetype

You had a @ in the variable before, did you try without that?

Thanks kip, that did it.

Yeah Jeavon tried it noth with and without

var myLink = fieldset.GetValue<int>("slideLink");

and

var myLink = @fieldset.GetValue<int>("slideLink");

Ok, I will investigate further. In the meantime to avoid obsolete umbraco.library this should work:

   <a href="@Umbraco.NiceUrl(int.Parse(myLink))">Click</a>

Yup, thanks

I've just tried this and it worked fine:

@foreach (var fieldset in Model.Content.GetPropertyValue<ArchetypeModel>("myarchetype"))
{
    if (fieldset.HasValue("slideLink"))
    {
        var myLink = fieldset.GetValue<int>("slideLink");
        <a href="@Umbraco.NiceUrl(myLink)">Click</a>
    }
}

So, I'm going to guess that you had a slideLink without a value. Adding the fieldset.HasValue deals with this to prevent the exception.

Well... I had to change the for each, because i wanted to check if a node was first... So i have:

@{
     var slider = Model.Content.GetPropertyValue<ArchetypeModel>("slider");
     foreach (var fieldset in slider)
    {
        if (fieldset.Equals(slider.First()))
        {
        <div class="item active">
            <div class="carousel-caption">
              @{ 
                    var myLink = @fieldset.GetValue("slideLink");
                }
                <a href="@Umbraco.NiceUrl(int.Parse(myLink))"><p>@Html.Raw(myStrippedText)</p></a>
            </div>    
        </div>
       }
    }
} 

and adding the <int> here causes an error...

How about like this:

@{
    var slider = Model.Content.GetPropertyValue<ArchetypeModel>("slider");
    foreach (var fieldset in slider)
    {
        if (fieldset.Equals(slider.First()))
        {
            <div class="item active">
                <div class="carousel-caption">                 
                    @if (fieldset.HasValue("slideLink"))
                    {
                        var myLink = fieldset.GetValue<int>("slideLink");
                        <a href="@Umbraco.NiceUrl(myLink)"><p>something</p></a>
                    }                   
                </div>
            </div>
        }
    }
}       

is working on a reply...
