GoogleMapControl @ + CustomMaps

Jul 4, 2009 at 10:45 AM

I was looking at your source code and it really looks rather similar to another GoogleMapControl at

Is there any relation between these two projects?

Also, I did not see it in the examples, but is there a way to create custom maps? or custom layers? What I'd like to do is point to a service that returns images and have them displayed as a layer on top of current images.

Also, what about opacity control on the maps?

Ciao Alberto,

it looks like GoogleMap Control cannot be used in a page where there's also an updatepanel (see so I have to switch to a different one. DO you have any experience with's one? Particularly about the possibility to use it with (or even better within) updatepanel?

This project is not related to the one you pointed.
I have answered already to that question.
You can see the full history of this project here under source.
I didn't worked with or even tryed the other project.
However, I have developed this project widely driven by the people's requests for functionality needed.
So, it could be possible I was driven and asked to implement in some cases a functionality similar to the other control.
Honestly, I have no idea how similar functionality this project has to the other, becuase I don't not the other in details.

Hi Velio and thanks for your reply.
Actually I have been playing with both your control and for a few weeks now.

I think your control is very well documented with examples that show you how to do things, and this is its strength.
However, when it comes to features and flexibility, I think is superior in that is allows a user like me to
see sky data and custom layers, etc.

Sadly neither does what I really need in a compact, easy to use, complete fashion so we have decided to move to a Flash base or Silverlight based type of application for
my astronomical needs.
