    <p>I have a problem with entity association refresh. When I get an entity with like this:</p> <pre><code>MyContext context = new MyContext(); Person myPerson = context.PersonSet.FirstOrDefault(); String myPersonName = myPerson.Name; Address myPersonAddress = myPerson.Address; </code></pre> <p>I got an a person with an association named Address and a property named Name. If I modify manually the datas in database for example the property Name, I have to use the following code to reload my entity:</p> <pre><code>context.Entry(myPerson).Reload(); </code></pre> <p>and I have the new value for Name. But If I do the same for Address it doesn't work. I think it is because Address is an association property. I need to refresh it. </p> <p>How Can I do to force the reload of Address association (and all other association in Person class) ?</p> <p>EDIT:</p> <p>In the same case, a person can have more than one address. </p> <pre><code>MyContext context = new MyContext(); Person myPerson = context.PersonSet.FirstOrDefault(); String myPersonName = myPerson.Name; List&lt;Address&gt; myPersonAddresses = myPerson.Addresses; </code></pre> <p>In this case, it is not a Reference:</p> <pre><code>context.Entry(myPerson).Reference(p =&gt; p.Address).Load(); // Address will be populated with only the new address // this isn't required because I use lazy loading </code></pre> <p>but a Collection:</p> <pre><code>context.Entry(myPerson).Collection(p =&gt; p.Addresses).Load(); // Address will be populated with old value and new value </code></pre> <p>I need to use this to work: </p> <pre><code>context.Entry(myPerson).Collection(p =&gt; p.Addresses).CurrentValue.Clear(); context.Entry(myPerson).Collection(p =&gt; p.Addresses).Load(); </code></pre> <p>But it doesn't seem to be a good solution to do this for all my navigation properties!</p>

    1. CODo you mean that `context.Entry(myPersonAddress).Reload()` does **not** work?

    2. COyes it means that DOESN'T work. Because this method reload only the property (=Name) and not the association (=Address)

    3. COAh, sorry I misunderstood. So, you don't want to reload the scalar properties of the same `Address` entity but the relationship to possibly another `Address` entity. Hm, good question...

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.
