How to get the parent content Node's name according to it's specific children doctype type
Hi everyone,

Need some help to query the parent Node name from the content structure for the following sections :Blog post , music band and events sections which are rendered in the same template via their respective Macro scripts

Please find structure

- BlogPostContainer with doctype alias container
```
    some children nodes with doctype alias *post*
```
-MusicBandContainer with doctype alias container
```
    some children nodes with doctype alias *musicband*
```
-EventContainer with doctype alias container
```
    some children nodes with doctype alias *event*
```
```
var container =  Model.Content.Descendants().FirstOrDefault(x=>x.DocumentTypeAlias=="container");
var containerName = container.HasProperty("containerTitle") && container.HasValue("containerTitle")? container.GetPropertyValue<string>("containerTitle") : container.Name. ;
```
//this return me the first container Name which is BlogPost in the razor script for blog list since this was the first container to be created in the content structure

For the other two section music band and event, i want to get their respective parent name also according to their specific children doctype
```
  @Model.Content.ChildrenAsList.Where("musicband").Parent.Name
```
//not working error

Thank you for kind response and help.

Simply put @Model.Content.ChildrenAsList.Where("musicband").Parent.Name doesnt work because ChildrenAsList returns a List

.Parent is a property available on IPublishedContent, so you will have to do a foreach on the collection.

Another issue is that you are using Descendants for a container/area kind of thing. Do you have containers inside containers ? If so, this can be the right.

So going out from the following structure.
- Node where you run this code on
  - Container A
    
    Item A1
    
    Item A2
    
    Item AX
  - Container B
    
    Item B1
    
    Item B2
    
    Item BX
  - Container C
    
    Item C1
    
    Item C2
    
    Item CX
- Another node
I would do:
```
//when you pass a string into the childrin function on an IPublishedContant, you filter on that documentTypeAlias
    foreach( var container in Model.Content.Children("container")
    {
        var containerName = container.HasProperty("containerTitle") && container.HasValue("containerTitle")? container.GetPropertyValue<string>("containerTitle") : container.Name. ;
    }
```

Hi Sven,

Thanks you very much for kind help.

Indeed this will return me a list of content nodes with the document type alias container . Indeed i dont need to use descendant as i wont have a container within another container.

Since i need to display each section's name in the same template, i finally got the following 2 possible solutions as shown below ,

Here is the content structure below :-

Under EN content structure i have the following
- EN Node
  - Container A (doctype alias container)
    
    List item A1 (doctype alias musicband)
    
    List item A2 (doctype alias musicband)
    
    List item AX (doctype alias musicband)
  - Container B(doctype alias container)
    
    List item B1 (doctype alias event)
    
    List item B2 (doctype alias event)
    
    List item BX (doctype alias event)
  - Container C(doctype alias container)
    
    List item C1 (doctype alias post)
    
    List item C2 (doctype alias post)
    
    List item CX (doctype alias post)
1.First solution : - assuming the each section name remains the same in my multi language website

List all container that contains the content name music band
```
var containerList = Model.Content.Children("container") .Where(x => x.Name.ToString().Contains("Music Band") );
```
Display the section name of music band
```
<h2>
@foreach(var container in containerList){
var containerName = container.HasProperty("containerTitle") && container.HasValue("containerTitle")? container.GetPropertyValue<string>("containerTitle") : container.Name;

      @Html.Raw(containerName)
}
</h2>
```
Another solution that i got is

to List all musicband nodes then check if parent doctype alias is container then break out the loop
```
foreach(var container in Model.Content.Descendants().Where(x=>x.DocumentTypeAlias=="musicband")){
                 if(container.Parent.DocumentTypeAlias=="container"){

                     var containerName = container.Parent.HasProperty("containerTitle") && container.Parent.HasValue("containerTitle")? container.Parent.GetPropertyValue<string>("containerTitle") : container.Parent.Name;
                    <h2>                                    
                      @Html.Raw(containerName)
                   </h2>
                       break;
                }
         }
```
Again thanks for your time and clean out my problem. Have a great weekend.
