Behavior Missing References?

BrianLeroux — Thu, 27 Dec 2012 19:31:37 GMT

I am trying to create my first behavior using silverlight 3.0 api and silverlight 5. For some reason I have an error with "[Export(typeof(Behavior<Map>))]" saying that I have a missing type or namespace. I also have the same issue on base.OnAttached();. I am taking these from the Zoom to Selected Layer sample. Anyone have any ideas.

using System; using System.Net; using System.Windows; using System.Windows.Controls; using System.Windows.Documents; using System.Windows.Ink; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Animation; using System.Windows.Shapes; //using System.Windows.Interactivity; using System.ComponentModel.Composition; using ESRI.ArcGIS.Client; using ESRI.ArcGIS.Client.Extensibility; using ESRI.ArcGIS.Client.Geometry; using ESRI.ArcGIS.Client.Tasks; using ESRI.ArcGIS.Client.Behaviors; using System.Windows.Threading;  namespace ECFMapLoad.AddIns {     [Export(typeof(Behavior<Map>))]     [DisplayName("Load ECF Data")]     public class MyBehavior : Behavior<Map>     {                 #region Behavior Overrides         protected override void OnAttached()         {             base.OnAttached();             // Show saved configuration text             MapApplication.Current.Initialized += Initialized;                      }          private void Initialized(object sender, EventArgs args)         {                      }         protected override void OnDetaching()         {             // Detach the event handler             MapApplication.Current.Initialized -= Initialized;             base.OnDetaching();                     }                          #endregion     } }

Hi Brian,

You'll definitely need the using statement for System.Windows.Interactivity, since that's what gives access to the Behaviors. You might want to try starting from a blank Visual Studio template and using the MyBehavior.cs file that is included as an example.

Also, double-check that you have the Microsoft Expression Blend Preview for Silverlight 5 installed.

I did not install Microsoft Expression Blend Preview for Silverlight 5 after I upgraded everything. I guessed I missed that step. Thank you!
