Getting a VortoValue from a specific node
Hello guys,

I just started off with Razor and i am running into all kinds of trouble and i was hoping you could help me along my way. I always work with XSLT but for this project we decided to use Razor because of Vorto (specifically made for Multilingual sites).

I'm trying to do something really simple but i can't find any documentation on how to do it. I want to make a list with childpages from a specific page. How would i go around doing this by using id instead of the current selection i'm using. I also want to use the same selection to add the value of a field inside that specific node as h2.
```
@using  Our.Umbraco.Vorto.Extensions
@inherits Umbraco.Web.Macros.PartialViewMacroPage
@{var selection = CurrentPage.Site().FirstChild("Modules").Children("Module");}
<h2></h2>
<ul>
@foreach(var item in selection){
IPublishedContent sitem= (IPublishedContent)item;
    <li><a href="@item.Url">@sitem.GetVortoValue("paginatitel")</a></li>
} 
</ul>
```

Hi Lex,

you can get children from a specific page by using
```
IPublishContent[] children = UmbracoContext.Current.ContentCache.GetById(1234).Children("Module");
```
You can get properties from child-node this way:
```
<h2>@(Model.GetPropertyValue("propertyAlias"))</h2>
```
Question! Why are you using the sitem var instead af using the item? You could go:
```
@foreach(IPublishContent item in selection) { 
    <li><a href="@item.Url">@item.GetVortoValue("paginatitel")</a></li>
}
```
I haven´t tested the code, but it schould work.

Hi René,

Thank you for your reply. Could you show me how to put this all together, because the problem i keep having when constructing Razor is that i somehow do something wrong which makes my macro fail.

I am using the @sitem because of

Hi Lex,

i hardly use MacroPartials anymore. But i can try giving it a go. I presume you are using a macroparameter to set the id of the parent node.

@inherits Umbraco.Web.Macros.PartialViewMacroPage
@{
    var id = 0;

    // get id from ex. contentPicker datatype on macro
    int.TryParse(Model.MacroParameters["parentNode"].ToString(), out id);

    // get IPublishContent object from id
    IPublishedContent parent = UmbracoContext.Current.ContentCache.GetById(id);

    // get children by documenttype "Module"
    IPublishedContent[] children = parent.Children.Where(x => x.DocumentTypeAlias == "Module").ToArray();
}
<h2>@(parent.GetPropertyValue<string>("headline"))</h2>

@if (children.Any()){
    <ul>
        @foreach (IPublishedContent item in children)
        {
            <li><a href="@item.Url">@(item.GetPropertyValue<string>("pagetitle"))</a></li>
        }        
    </ul>
}

Hello René, i wasn't setting the id with a MacroParameter but as a hard value. So with a little bit of Googling i changed:
```
int.TryParse(Model.MacroParameters["parentNode"].ToString(), out id);
```
To:
```
int.TryParse(1128.ToString(), out id);
```
Which works perfect. Thank you so much for your help René!

Hi Lex,

great you got it working! :-)

Extra bonus info: you don´t need to int.TryParse when you hardcode the id. So you can do just:

@inherits Umbraco.Web.Macros.PartialViewMacroPage @{ // get IPublishContent object from id IPublishedContent parent = UmbracoContext.Current.ContentCache.GetById(1128);

// get children by documenttype "Module"
IPublishedContent[] children = parent.Children.Where(x => x.DocumentTypeAlias == "Module").ToArray();
}
