ToggleLayerAction

okay I must officially be going crazy,

I found this wonderful little action and low and behold, my layer only toggles on/off
1. after you pan the map, and/or
2. evertime after the first (no need to pan)

anyone else have a similar issue?

<Button x:Name="MTWater"
                                    Style="{StaticResource MenuItem}"
                                    Content="Map Tip Water">
                                <i:Interaction.Triggers>
                                    <i:EventTrigger EventName="Click">
                                        <esriBehaviors:ToggleLayerAction LayerID="FLWaterLines" TargetName="MyMap"/>
                                    </i:EventTrigger>
                                    <!--<i:EventTrigger>
                                        <esriBehaviors:UpdateFeatureLayerAction FeatureLayerID="FLWaterLines" TargetName="MyMap"/>
                                    </i:EventTrigger>-->
                                </i:Interaction.Triggers>
                            </Button>

further,

if I start with the Layer Visible = true, it turns off okay at first attempt.
if I start with the Layer Visible = false, it won't turn on at first attempt until the map is panned.

I didn't reproduce the issue.

I changed this interactive sample http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#LayerActions in order to start with a non visible layer and the layer turns on at first attempt when clicking the ToggleLayer action.

Could you give more infos on how to reproduce this issue?

Thanks

Thanks for checking,

Can you verify with a FeatrureLayer using OnDemand and a MaxResolution set (yes I was below this resolution when I first tryed to turn it on).

<esri:FeatureLayer ID="FLWaterLines" Url="http://***/rest/services/GIS_App_ENG/MapServer/2"
                                       FeatureSymbol="{StaticResource LineWaterBlue}" Mode="OnDemand" OutFields="*" MaximumResolution="3"
                                       Visible="False" x:Name="FLWL" Where="WATERLINETYPE='WATERMAIN'">

<Button x:Name="MTWater"
                                    Style="{StaticResource MenuItem}"
                                    Content="Map Tip Water">
                                <i:Interaction.Triggers>
                                    <i:EventTrigger EventName="Click">
                                        <esriBehaviors:ToggleLayerAction LayerID="FLWaterLines" TargetName="MyMap"/>
                                    </i:EventTrigger>
                                </i:Interaction.Triggers>
                            </Button>

Thanks again

I was eventually able to reproduce the issue with a feature layer but only with 2.1 version. Looks working well with version 2.2.

Which version are you using? If 2.1, could you give a try with 2.2?

Thanks

Thanks for your efforts.

I am meaning to go to 2.2 soon, hopefully this week, so I will repost my findings.

2.2 has cleared this up for us, 😉 great work.

Thanks again.
