    1. COIs there a chance that your making a round trip to the server, posing the data, and getting back a new view, with no model and hence a blank form? In my experience, the validators will never "erase" any values in the form, thats just not how it works.

    2. COnow that you mention it it makes sense i guess it's related to my other post : http://stackoverflow.com/questions/8435583/asp-net-mv3-form-post-data-not-making-its-way-to-the-controller-action. Since my form is not posted the view is reloaded with empty fields. my model is invalid since all field did not fill from the form/model binder and it reload the page with empty fields

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).
