i am currently doing a silverlight c# application , following a sample code in the arcgis website, i added this code in the xaml page to add the constrainextent function. there is no other code in the xaml.cs page.
<i:Interaction.Behaviors> <esriBehaviors:ConstrainExtentBehavior ConstrainedExtent="-120,30,-60,60" /> </i:Interaction.Behaviors>
however it gives me this error, A value of type 'ConstrainExtentBehavior' cannot be added to a collection or dictionary of type 'BehaviorCollection'.
could anyone help me to solve this? this is my xaml page if there is any code i need to add in , i am a beginner in this section and have posted questions before but cant get a working solution for this.
