    <p>A record is uniquely identified by its <code>Kind</code> and <code>RecordId</code>. </p> <p>I have a set of records that I want to display as a dropdown, and on submitting I'd like to get <code>SelectedKind</code> and <code>SelectedRecordId</code> for further processing.</p> <p>The problem is, <strong>I want these values to be processed separately, but there should be only one dropdown</strong>.<br> What is the best practice for doing this?</p> <p>My suggestions:</p> <h3>Option 1</h3> <p><strong>Populate the dropdown with strings like <code>"Kind_RecordId"</code> and set up a JavaScript <code>change</code> handler which will parse the string and set hidden field values.</strong></p> <p>However I don't quite like the idea of having string operation logic in different places (in controller when populating the dropdown, and in view when parsing the values). Should I move <code>SelectItem</code> populating logic into view as well, and keep my business objects in the view model instead?</p> <p>It also bugs me that in rare case when JavaScript is disabled, the user will not be able to sumbit the form at all.</p> <h3>Option 2</h3> <p><strong>Expose a unique <code>"Kind_RecordId"</code>-like string property in my form model, and let the model parse it (or fill it) through strong-typed accessor properties for the controller?</strong></p> <p>This seems like a better way but I'm not entirely sure. What I consider good about it is it'll keep all parsing/concatenating logic in view model, and it will not fail when JavaScript is not available.</p> <p>Community thoughts are very appreciated.</p>

    1. COSo will users be selecting from any combination of Kind and RecordId? Meaning, if there are 3 kinds and 4 record ids they can select from 12 drop down items?

    2. CONo, there won't be two different lists at all. You can think of it as of a composite key.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
