"'esriBehaviors' is an undeclared prefix. Line 31, position 18"

First be sure you have added ESRI.ArcGIS.Client.Behaviors as a reference in your project.

Then you have to declare the prefix you are using :

xmlns:esriBehaviors="clr-namespace:ESRI.ArcGIS.Client.Behaviors;assembly=ESRI.ArcGIS.Client.Behaviors"

As an easier alternative, you can use the generic esri prefix identified by an URI:

   xmlns:esri="http://schemas.esri.com/arcgis/client/2009"
