    <p>I think you can do that. Just above your property in the model table add the StringLength Attribute. Just like following. (Remember you will need to include using System.ComponentModel.DataAnnotations;)</p> <pre><code> [StringLength(160)] public string Title { get; set; } </code></pre> <p><strong>Update</strong></p> <ul> <li><p>First of all, You cannot create an index on an nvarchar(MAX) column. You can use full-text indexing, but you cannot create an index on the column to improve query performance. </p></li> <li><p>From the storage prospective there are no difference between nvarchar(max) and nvarchar(N) when N &lt; 4000. Data is stored in row or on the Row-overflow pages when does not fit. When you use nvarchar(max) and stores more than 4000 characters (8000 bytes) SQL Server uses different method to store the data - similar to old TEXT data type - it stores in the LOB pages.</p></li> <li><p>Performance-wise - again, for N&lt;4000 and (max) - there is no difference. Well, technically it affects row size estimation and could introduce some issues - you can read more about it here: <a href="http://aboutsqlserver.com/2010/08/18/what-is-the-optimal-size-for-variable-width-columns/" rel="nofollow">Optimal way for vaiable width colums</a></p></li> <li><p>What can affect the performance of the system is the row size. If you have queries that SCAN table, large row size will lead to more data pages per table -> more io operations -> performance degradation. If this is the case, you can try to do the vertical partitioning and move nvarchar field to the different table. </p></li> </ul>

    1. POIs there a way to override the nvarchar(max) with a set maxlength value using EF 4.2 codefirst configuration?

    1. COHi, I was looking for a global convention.

    2. COThe global convention is the use of nvarchar(MAX) only. All you can do is to override it individually and that's how it should be. If you want all your string properties in the project to have a fixed length, then why not add a function or class that detects the string properties in a model class and attach the StringLenth Attribute for you

    3. COThat is the default global convention, I was looking to override it and set my own for my project. nvarchar(MAX) has downsides that I don't want to impact my project should I need to optimise it at the database level in the future i.e. no indexing of nvarchar(MAX) columns.

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.
