Check if Multi-URL picker has items

Razor

Hi,

I am trying to create an unordered list, which will not show if the content editor has not added an items to the list.

I have the following code:

<umbraco:Macro Language="cshtml" runat="server">
                      @if (@Model.HasProperty("upperListLinks") && @Model.GetProperty("upperListLinks").Value != String.Empty)
                      {
                        <ul class="green_squers">
                        @foreach (var link in Model.upperListLinks.urlpicker) {
                            <li><a href="@link.url" @Html.Raw(link.newwindow == "True" ? "target=\"_blank\"" : "")>@link.linktitle</a></li>
                        }
                      </ul>
                      }
                  </umbraco:Macro>

Any ideas on how I can get this to work?

Thank you!

If the Multi Url Picker's alias is upperListLinks, then the following should work:

@using umbraco.MacroEngines
@inherits DynamicNodeContext
@if (Model.upperListLinks.GetType() == typeof(DynamicXml) && Model.upperListLinks.Count() > 0)
{
    <ul class="green_squers">
    @foreach (var link in Model.upperListLinks) {
        <li><a href="@link.url" @Html.Raw(link.newwindow == "True" ? "target=\"_blank\"" : "")>@link.linktitle</a></li>
    }
    </ul>
}

If the current Model does not have a Multi Url Picker with the alias of upperListLinks, then Model.upperListLinks.GetType() will return a DynamicNull object and the condition will be false.
