SL4 Breaks ESRI Behaviors

PatrickBrooke

Hello all,

Unless it is just me, which i sincerely hope it is, SL4 breaks the Measure Action and Constrained Extent Behavior. I will attach my constrained extent behavior code, but it is the same as the ESRI sample, a pretty basic feature. The same code works just great in SL3. Strange Error. Measure Action is much the same. I realize the ESRI tools for SL are developed on SL3, but am hoping to push my new site out in the next week or 2 in SL4. Mainly upgrading for the print functionality. Worth it!

The error message:

"A value type of 'ConstrainExtentBehavior' cannot be added to a collection or dictionary of type 'BehaviorCollection'"

Code:

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

<i:Interaction.Behaviors>
                <esriBehaviors:ConstrainExtentBehavior ConstrainedExtent="-120,30,-60,60" />
  </i:Interaction.Behaviors>

hi patrickbrooke
I had the same problem as yours and i implemented  it with code (insert this snippet in loaded event) and it works (I don't know why???)

System.Windows.Interactivity.Behavior behavior = new ESRI.ArcGIS.Client.Behaviors.ConstrainExtentBehavior()
            {
            ConstrainedExtent = new ESRI.ArcGIS.Client.Geometry.Envelope(-120,30,-60,60)
            };
System.Windows.Interactivity.Interaction.GetBehaviors(Map).Add(behavior);
