silverlight maptips

lyndamccallum — Wed, 01 Dec 2010 12:15:03 GMT

I'm having an on going problem with maptips.

I have the follow layers defined in my xaml file where MyFeatureLayer is the maptips layer.

<esri:ArcGISTiledMapServiceLayer ID="BaseMap" Url="{StaticResource BaseMap}" ></esri:ArcGISTiledMapServiceLayer>
            <esri:ArcGISDynamicMapServiceLayer ID="BaseLayer" Url="{StaticResource WDPurl}"></esri:ArcGISDynamicMapServiceLayer>

            <esri:GraphicsLayer ID="MyGraphicsLayer"/>
            <esri:GraphicsLayer ID="FlashFeatureLayer"/>


            <esri:FeatureLayer ID="MyFeatureLayer" Url="{StaticResource FacilitiesLayerID}" FeatureSymbol="{StaticResource DefaultNoMarkerSymbol}" >

The problem is every time I put something in mygraphicslayer over an existing point, the maptip for the existing point won't say open long enough to allow me to click on the link within it. All points that are not covered with a feature in the mygraphicslayer work fine. Any ideas?

Another wierd thing is that I don't experience this behaviour when I run in debug mode only once the site is published.

Thanks

Be sure that your maptip framework element has:
      - IsHitTestVisible set to true
      - a background not null
      - a MapTipHideDelay > 0

If this doesn't help, please share how your maptip looks like.

Here is my xaml for it

I am not sure that your border has a background (depending on how is defined you CommonBorder style).

Please try by setting a background explicitely.

Something like :

 
<Border esri:GraphicsLayer.MapTipHideDelay="00:00:01.5" Background="White" Padding="10,3,10,3" Effect="{StaticResource dropShadow}" IsHitTestVisible="True" >
......

 
<Border esri:GraphicsLayer.MapTipHideDelay="00:00:01.5" Background="Transparent"  Style="{StaticResource CommonBorder}" Padding="10,3,10,3" Effect="{StaticResource dropShadow}" IsHitTestVisible="True" >

yes it has a background. It i set it to white as in your code then it covers over the data in the maptip

Re: silverlight maptips

DominiqueBroux — Wed, 01 Dec 2010 20:17:51 GMT

But with the White background, does the maptip stay open or not?

Re: silverlight maptips

lyndamccallum — Thu, 02 Dec 2010 11:19:33 GMT

no it doesn't stay open

Re: silverlight maptips

DominiqueBroux — Thu, 02 Dec 2010 18:03:17 GMT

Sorry, I am in lack of idea.

With my version, I don't reproduce the behavior after setting a background.

Which API version are you using?

Re: silverlight maptips

lyndamccallum — Thu, 02 Dec 2010 19:14:06 GMT

I'm using arcgis server 9.3.1, and i believe silverlight api 1.2

Re: silverlight maptips

lyndamccallum — Thu, 02 Dec 2010 19:39:57 GMT

sorry i'm using 1.1

You might want to upgrade to v2.1 (if you can use SL4), there had been some bug fixes and other enhancements.

What's new in 2.1 http://help.arcgis.com/en/webapi/silverlight/help/index.html#/What_s_new_in_2_1/016600000025000000/ includes this bug fix:
When MapTipHideDelay > 0, a MapTip disappears despite cursor still being on top of the MapTip upon initial mouse hover

You may be experiencing that the map tip does not remain open on initial mouse over, the succeeding mouse over should be okay. If however, you never see the map tip open at all, then it is a different issue altogether.
