    How would I get all child nodes of selected nodes in treepicker as one selection

    Using Umbraco And Getting Started
    Umbraco 8

    Hi I would like to build a query that would get all children of the parent nodes selected in a multitreepicker.

    So if I had a treepicker that selects categories, how would I return a single collection of all proucts from all of the nodes selected.

    Regards

    Hi,

    I think you could do something like this:

    var allChildNodes = parentNodes.SelectMany(x => x.Children);

    parentNodes is the list of selected items from the MultiNodeTreePicker.

    Perfect. Thankyou.

    First pass of code.

    @{
var parentNodes = Model.Value<IEnumerable<IPublishedContent>>("relatedCollections");
if(parentNodes != null ){
var productSelection = parentNodes.SelectMany(x => x.Children);
foreach(var productItem in productSelection){
<p><a href="@productItem.Url">@productItem.Name</a></p>
}}}

    Where relatedCollections is the MultiNode TreePicker.

    Gives the required collection.

    Cheers :)
