[ZahidCheema]

When we click on a marker graphics, a popup show information about the pop. I want to do the same thing manually. I mean, I ll give lat and lon input and a pop up should show on a button click.

Dear thanks for you reply. Actually t looks a bit helpless for me. I just want to perform click event on a marker on the map by giving Latitude and Longitude as input to this event in Java.

Hello Zahid,

Here is the code and it works. I am not sure which programming language you are using but you could convert it.

Thanks,

James
