DataList: How to get nodes with selected item(s)

[greystate]

Hi there 👋

Looking for some advice/pointers regarding the issue of selecting nodes that have certain values selected in a DataList property editor.

For example, if I've been using a DataList for selecting some "available in" countries on a product node, is there a recommended way to efficiently select the products that include a specific country in their selection? Would it make sense (or even possible) to have a built-in method to do this?

I can use various versions of the traversal methods to get at them (XPath might even work well, depending on the PropertyValueConverters) - but of course I worry about their efficiency, as there seem to always someone who knows "a better way" 😁

@greystate Would the Examine data-source be useful? e.g. +availableIn: GB +availableIn: DK

(It's currently sorely undocumented - but hopefully the in-datatype instructions will make sense)

Thanks @leekelleher — I haven't dared trying that one yet 😬 - though for this, I was thinking of how to grab the selected nodes in code (e.g. in a View)... I seem to remember nuPickers provided some trickery to ease that part 🤔

It's one of those "flexibility vs simplicity" cases, because the Examine data-source lets you set what the value of the Examine result can be, it's up to you how you deal with it on the frontend.

The default value is set to __Key, which is the Guid for the content node, so on the frontend, a call to something like var content = Umbraco.Content(value); should do it. 🤞
