Umbraco 7, build navigation from MultiNode Tree Picker?
How do use the MultiNode Tree Picker in Umbraco 7 to build a navigation. I am trying to use a PartialView. We used to do a MacroScript but wanted to try my hand at the MVC and Partial views.
My code is below but it just keeps not rendering. I have the MultiNode Tree picker set up on a Node as a property but I keep getting a customError page via MVC. I don't quite understand where it is breaking. I even try to just print out the name of my var 'mainNavi' (below) and that gives me nothing. Any ideas?
My current code is:
@{
var mainNavi = Umbraco.Content(1544);
}
<div id="mainNavTop">
<nav class="left">
<ul id="mainNav">
@foreach (var x in @mainNavi.mainNavigationPicker)
{
var page = Umbraco.Content(x.InnerText);
var firstSubLevel = page.Children.Where("template!=0").Where("Visible");
var selected = Array.IndexOf(CurrentPage.Path.Split(','), page.Id.ToString()) >= 0 ? " class=\"selected\"" : "";
<li>@page.Name
@*
@if (firstSubLevel.Count() > 0)
{
<ul class="subNavFirst">
@foreach (var secondPage in firstSubLevel)
{
var subSelect = Array.IndexOf(Model.Path.Split(','), secondPage.Id.ToString()) >= 0 ? " class=\"selected\"" : "";
<[email protected](subSelect)>@NavLevel(@secondPage)</li>
}
</ul>
}*@
</li>
}
</ul>
</nav>
</div>
<!-- END MAIN NAV -->
@*HELPERS*@
@helper NavLevel(dynamic page)
{
if(page.NodeTypeAlias == "Redirect")
{
if (page.HasValue("alternateNavigationName"))
{
if(page.openInNewWindow){
<a href="@page.redirectURL" target="_blank">@page.alternateNavigationName</a>
}else{
<a href="@page.redirectURL">@page.alternateNavigationName</a>
}
}
else
{
if(page.openInNewWindow){
<a href="@page.redirectURL" target="_blank">@page.Name</a>
}else{
<a href="@page.redirectURL">@page.Name</a>
}
}
}
else
{
if (page.HasValue("alternateNavigationName"))
{
<a href="@page.Url">@page.alternateNavigationName</a>
}
else
{
<a href="@page.Url">@page.Name</a>
}
}
}
You would be correct in your thinking. I just had to clean up some code and I was going to post my code here. But your find lead me to the right direction.

@Steve,
You would be correct in your thinking. I just had to clean up some code and I was going to post my code here. But your find lead me to the right direction.
My solution for our implementation.
@inherits Umbraco.Web.Mvc.UmbracoTemplatePage @*Top level navigation new structure*@ @{ var naviList = Umbraco.Content(1544).mainNavigationPicker.ToString().Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries); var naviCollection = Umbraco.Content(naviList); <div id="mainNavTop"> <nav class="left"> <ul id="mainNav"> @foreach (var item in naviCollection) { var firstSubLevel = @item.Children.Where("Visible"); <li class="@(item.IsAncestorOrSelf(CurrentPage) ? "selected" : null)"> @NavLevel(@item) @if (firstSubLevel.Count() > 0) { <ul class="subNavFirst"> @foreach (var secondPage in firstSubLevel) { <li class="@(secondPage.IsAncestorOrSelf(CurrentPage) ? "subSelected" : null)"> @NavLevel(@secondPage) </li> } </ul> } </li> } </ul> </nav> </div> } @*HELPERS*@ @helper NavLevel(dynamic item) { if(item.NodeTypeAlias == "Redirect") { if (item.HasValue("alternateNavigationName")) { if(item.openInNewWindow){ <a href="@item.redirectURL" target="_blank">@item.alternateNavigationName</a> }else{ <a href="@item.redirectURL">@item.alternateNavigationName</a> } } else { if(item.openInNewWindow){ <a href="@item.redirectURL" target="_blank">@item.Name</a> }else{ <a href="@item.redirectURL">@item.Name</a> } } } else { if (item.HasValue("alternateNavigationName")) { <a href="@item.Url">@item.alternateNavigationName</a> } else { <a href="@item.Url">@item.Name</a> } } }is working on a reply...
