    1. COSo what is the question? Are you asking what code to put into the `saveItemCompleted` and `saveItemFailed` handlers? Do you just want to display the message in a popup or something or do you want the partial view to be re-rendered?

    3. COUsually when we call a controller via ajax and get back a `PartialView` we take the result and put it some place on the form such as `$('#myTargetDiv').html(data);` Have you used the javascript debugger to look at the result (`data`) from your ajax call?

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.

SQuiL has stopped working due to an internal error.

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