Hi Yasir,
Thank you for contacting Syncfusion support.
We can notify the marker click in maps using markerclick event. This event will be triggered when we click on a marker in the Maps control. We can also add images as a marker using "imageUrl" property of the markerSettings property. We have create a simple sample to demonstrate the same and it can be downloaded from the following link.
In the above sample, we have rendered a map control with markers as images. We have added the markerClick event in the control and a simple alert message will be shown when the marker is clicked.
Please let us know if you need any further assistance.
Regards,
Sharmi M.
