MeasureAction problem

[ThaoNguyen]

I tried to use MeasureAction and got the following error:

A value of type 'MeasureAction' cannot be added to a collection or dictionary of type 'TriggerActionCollection'.

My code:
<i:Interaction.Triggers>
                            <i:EventTrigger EventName="Click" x:Uid="eventTrigger">
                                <esriBehaviors:MeasureAction x:Uid="measureAct"                               
                                    AreaUnit="SquareMiles"
                                    DisplayTotals="True"
                                    DistanceUnit="Miles"
                                    MapUnits="Meters"
                                    MeasureMode="Polygon"                                  
                                    FillSymbol="{StaticResource DefaultFillSymbol}"
                                    TargetName="MainMap"/>
                            </i:EventTrigger>
                        </i:Interaction.Triggers>

Namespaces:
xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"  
    xmlns:esriBehaviors="clr-namespace:ESRI.ArcGIS.Client.Actions;assembly=ESRI.ArcGIS.Client.Behaviors"

At first I referenced namespace esriBehaviors to ESRI.ArcGIS.Client.Behaviors but found out that MeasureAction class is in Client.Actions namespace.

Please help!  Thanks!

Are you using v2.0 or higher? If so, you can reference esri assemblies this way:

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

Have you looked at the SDK sample for MeasureAction? http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#UtilityActions

I'm not sure why you use x:Uid instead of x:Name but the error message does not seem related to that. Maybe try updating your xaml namespace definition (as above) first.

Yes, I already tried xmlns:esri="http://schemas.esri.com/arcgis/client/2009" first, it didn't resolve the problem. 
I have to use x:uid.  I think it should not affect the esri map.  It is more a common thing in wpf anyway.

I had looked at the sample before I did all of this.  Actually, I'm learning what arcgis offers.

Found out that the attribute TargetName I specified in <MeasureAction> was not correct!

MeasureAction worked for arcgis 9 but NOT for arcgis 10 :(.

The tag 'MeasureAction' does not exist in XML namespace http://schemas.esri.com/arcgis/client/2009'.

I'm using Visual Studio 2010..any one get this working?

Try adding ESRI.ArcGIS.Client.Behaviors
