to display two images

Hi @dheerajkumar,

here is a simple example , which may be, could be helpful. It show only one possible solution (not the best- most efficient solution  but it works)

Following steps:

1.) create a thing /general thing with one boolen property e.g. IMAGE_ON:

2.) defined 3 services 

set_on                        - set the value of the property IMAGE_ON to true

set_off                        - set the value of the property IMAGE_ON to false

get_image_status  -returns the property value of  IMAGE_ON

3.) create a mashupe with 2 button for set_on and set_off and a  image

4.) bind the all data result of the service get_image_status to the visible property of image (here I used not the directl way where I set the state of a checkbox and later the checkbox has the binding to the visible property of the image)

5.) bind the buttons image_on/image_off  clicked event to the services set_on/set_off

6.) bind services set_on/set_off  ServiceInvokeCompleted  event to call the get_image_status. service.

Here we can see the steps in the picture below:

7.)I  tested it in mashup preview mode:
