There is a good simple solution for a multi-page "Wizard" control in MVC here: <a href="http://www.highoncoding.com/Articles/647_Creating_Wizard_Using_ASP_NET_MVC_Part_1.aspx" rel="nofollow noreferrer">http://www.highoncoding.com/Articles/647_Creating_Wizard_Using_ASP_NET_MVC_Part_1.aspx</a> <a href="http://www.highoncoding.com/Articles/652_Creating_Wizard_in_ASP_NET_MVC_Part_2.aspx" rel="nofollow noreferrer">http://www.highoncoding.com/Articles/652_Creating_Wizard_in_ASP_NET_MVC_Part_2.aspx</a> The model is populated in several steps and a hidden field is used to persist data between pages (somewhat similar to ViewState). However, with the release of MVC 2 RC2, the validation mechanism has been changed from "input validation" to "model validation": <a href="http://bradwilson.typepad.com/blog/2010/01/input-validation-vs-model-validation-in-aspnet-mvc.html" rel="nofollow noreferrer">http://bradwilson.typepad.com/blog/2010/01/input-validation-vs-model-validation-in-aspnet-mvc.html</a> Now the first page in the "Wizard" never gets validated, since it only populates part of the model. (The rest is to be populated during further steps, but since there can be required fields, validation errors are shown during the validation for the first page and the user can't proceed). Is there a way to modify this implementation of the "Wizard control" to suit MVC RC2, or should the whole logic be re-thought? Are there any better patterns for creating a multi-page "wizard control" for populating a model?

Guidance

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.
