On click LineString data

[MengeneeringSoft]

Hi,
I imported a GPX track into a map component and I drew the track LineString.

I need to click on a point of the LineString to get some informations : LAT, LON and ID of the point clicked.
Through the ID I could retrive other data like altitude ( I imported altitude data from GPX in a list).

There is no standard method to do this with LineString component.
Is there a way/extension/workaround to do this ?

Thanks

Line String Distance

The distanceLineString Procedure calculates the sum of all the LineString segments (or legs if you will) in your trak LineString. The procedure can be built using calls to either the distanceBetweenLocationsMiles Procedure or the distanceBetweenLocationsKilometers Procedure (depending on whether you want the distance in miles or kilometers). The Map1.DoubleTapAtPoint builds an example linestring. It is there only to demonstrate how the calculation of distance works in the demonstration…

It can store points, lines, and polygons, along with richer content like descriptions, images, and 3D…

I already checked theese links.
So there is no way to click a Linestring point and to get info about that point..........
