    Related links count

    In Razor, how do you check the number (count) of related links? For example,

    if(@Model.RelatedLinks.Count() > 0) { //do something }

    Thank you, in advance, for any help.

    Hi Sean,

    The only way I've been able to do this with Umbraco 4.7.0 is so...

    <umbraco:Macro  runat="server" language="cshtml">
@{
   int count = 0;
}
@foreach(var @item in Model.relatedLinks.link)
{
    count++;
}
@count
</umbraco:Macro>

    Ugly hack huh? I wouldn't suggest actually using this though... but it's the only way I could figure out how to get the count!

    I believe there have been hugely significant improvements to DynamicNode/DynamicXml in the upcoming Umbraco 4.7.1 release - hopefully there's a more elegant solution for this problem.

    Cheers, Lee.

    Yup, counting will be possible in 4.7.1. Just a few more weeks of patience, or use a nightly build. :)

    I tested this in Umbraco 4.11.3.1 and it works:

    @Model.RelatedLinks.Count() > 0

    Because I read that, for performance reason it's better to use the GetProperty("alias") on @Model, I tried:

    @Model.GetProperty("RelatedLinks").Count > 0

    but this generates an error.

    anyone knows why this fails?

    Thanks for your help,

    Anthony
