how to convert the kml xy values in to latitude, longtitude

[Asiq Raja]

Hi,

        Now i m using the telerik rad map for show the details, and want to bind the shape file, but unfortunately i m using telerik q1 version, so i can't able to directly use that shape file, so i convert that as a kml file format. Now its working but i using some sample kml data's which is provided by telerik examples. but  when i look a deep look in my converted kml file, i see the values are in X,Y Values, so that i don't know How to bind this values in to the rad map, even weather rad map ll support this values or not i don't know, So plz

Explain me how to handle this, and how to convert the XY values in to decimal  latitude & Longitude.

Are any way to bind the xy values directly in the rad map control, using kml file.

Thank you

Hello Asiq Raja,

I'm sorry, we were not able to follow your description completely. Could you, please, clarify -- what do you mean by "X,Y Values"? The KML file stores coordinates as "longitude,latitude" pairs. Could you, please, provide your converted KML file so we could take a look inside? 

Kind regards,

Hello Asiq Raja,

I have attached a sample solution which reads the kml-file to the information layer. It uses the MapShapeReader class to read shapes from the kml.

I hope it helps.

Hello Asiq Raja,

You can use MapShapeReader to read ESRI shape files as well. Simple pass URI of the shape file instead of name of the KML file.
