    <p>I have an error with my Xaml files in a WPF application. I'm not able to see my control in the Visual Studio designer or in Blend. But, the application compiles and is running perfectly. </p> <p>In Blend, it says that there's an invalid Xaml and the error just make no sens at all, but when I close the control there's no more error.</p> <p>In Visual Studio, the error is more explicit.</p> <pre><code>Error 27 Invalid XmlnsDeclaration occurs in assembly 'Microsoft.Expression.Interactivity, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. XmlnsDeclaration references a namespace 'Microsoft.Expression.Interactivity.Layout' that is not in the assembly. </code></pre> <p>I made my research on this error and I found some things interesting.</p> <p><strong>Solution 1</strong></p> <p>Create a dummy class with the namespace <em>Microsoft.Expression.Interactivity.Layout</em>.</p> <p>Result ? Not working.</p> <p><strong>Solution 2</strong> Using...</p> <pre><code>xmlns:i="clr-namespace:Microsoft.Expression.Interactivity;assembly=Microsoft.Expression.Interactivity" </code></pre> <p>Instead of</p> <pre><code>xmlns:i="http://schemas.microsoft.com/expression/2009/interactivity" </code></pre> <p>... to add my reference.</p> <p>Result ? I was already doing it this way.</p> <h2><strong>UPDATE</strong></h2> <p>Tried the reference to the schemas url only in Blend and still not working.</p> <p>Error : </p> <pre><code>"The specified value cannot be assigned to the collection. The following type was expected : "TriggerAction". </code></pre> <p>With this code : </p> <pre><code>&lt;interactivity:Interaction.Triggers&gt;&lt;interactivity:EventTrigger EventName="SelectionChanged" &gt;&lt;my:CommandAction Command="{Binding BreedingListSelectionChanged}" SyncOwnerIsEnabled="True" /&gt;&lt;/interactivity:EventTrigger&gt;&lt;/interactivity:Interaction.Triggers </code></pre> <hr> <p>Finally, I found <a href="http://forums.silverlight.net/forums/t/89257.aspx" rel="nofollow noreferrer">this post</a> by a guy from the Microsoft Only Community Support. He's saying that this it an known issue and it will probably be fix next release. </p> <p>The fact is, I need it right now.</p> <p>Anyone faced this problem ?</p> <p>Thanks. </p>

    1. CO1. Is your app's configuration AnyCPU and is the MS assembly AnyCPU (Blend only uses the AnyCPU)? 2. Have you tried defining CopyLocal=True on the reference to the assembly?

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.
