    Check if Multi-URL picker has items

    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.
