Hi Ashok,
For item 3, remove the data copyright is not allowed by data provider.
The other 2 questions don’t related with Google map, you can just implement by our map.
For item 1 we don’t have sample for that, and if you want to implement that you need to write some custom JavaScript code, you can search on forum and find some related topic for example: Mouse over marker and increase the size of the marker using Javascript
For item 2, You can open that like this: Map1.MapTools.MouseCoordinate.Enabled = true;
Regards,
Ethan
