Hi Nagendra,

You can add image in WDA dynamically. Check the below thread FYR.

But what exactly you are looking for??

Hi,

You can make use of TimedTrigger UI Element and set the delay as you required and on every trigger, try to change the image into the view.( So the event automatically triggered by TimedTrigger and your images keep changing )

Hi Nagendra,

You can merge all images into single GIF Image using Photoshop or some other tool, upload the GIF into WDA using MIME , it will be capable of showing multiple images again and again without any events.

Hi Nagendra,

How are planning to get the images into webdynpro ? are those uploaded into mime repository and respective urls are available  to fetch and bind to webdynpro image element?

May be its helpful if you go through the below document

In the above document its been demonstrated to put image into cache and then use it in image ui element.

Hi,

You can achieve your requirement as below

• Create a TimedTriggerUI element on view and create an event for it, also set delay viz 1 sec
• Create an context attribute IMAGE_SOURCE of type string
• Create an image ui element on view and bind the property "Image source" to the context attribute IMAGE_SOURCE
• Now on event handler of timed trigger, set the mime repository url/path as below

" Each time prepare the path of image

                    example:

                    data lv_path type string.

                         lv_path = 'hello.jpg'.

               " get the context element reference

                    lo_context_element = wd_context->get_element( ).

               " set the path of image source to attribute

               lo_context_element->set_attribute(

                              name = 'IMAGE_SOURCE'

                              value = lv_path ).

Hope this helps you.

Regards,

Rama
