question about dynamic maplayer url

SangamLama — Wed, 19 Jan 2011 17:22:46 GMT

Hello all,

I've been following the tutorial in ESRI Interactive SDK, where the map URL is hardcoded in the xaml side of SL page.

Now let's say there's a scenario where the map server is different for different users. In such a case, how can I add the map layer into my SL page?

As far as my attempt is concerned, I tried binding the map layer url as such:

<esri:ArcGISTiledMapServiceLayer x:Name="MapLayerUrl" ID="StreetMapLayer" Url="{Binding mapUrl}"/>

Its not working. InitializeComponent() in the constructor receives error from ESRI.ArcGIS.Client, which I'm assumig is expecting an absolute url string.

Any ideas?

Url is not a DependencyProperty that's why you cannot Bind to it. In addition to J's sample, you can also look at : http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#SwitchMap. The ArcGISTiledMapServiceLayer.Url is updated in code-behind.
