I want to Display a kml file in with the Javascript API.

It is working so far. But there are no names from the Point Features displayed on the map.

There is only the pin...

How i can Display the Name of the Point Feature above the pin?

the kml File: ny.kml

and the javascriptfile: index2.html

Thank you very much


 

ny.kml.zip
index2.html.zip

Stefan,

  By default a KMLLayer will take the label info from the KML and add it as the popup info (when you click on the feature). You can force it to label by adding a LabelClass to the KMLLayers internal FeatureLayer:
