Hello MariamSohail,
I suppose, you are using one instance of Extern Bitmap and all items share this one instance. As consequence, there will only be one image at the same time existing. I would propose:
1. For your list implement a separate component acting as item. It means, a component with the appearance of a a single list row. You don't need to use Attributed Text view. In the item you can compose the appearance of the item. For example, you can arrange an Image view and a Text view side by side to display the service logo and the service title.
2. Manage the Extern Bitmap object directly within the list item component (from the step above). In this manner each item manages its own Extern Image instance.
3. When loading the List Item in the OnLoadItem method, initialize the item with the name of the service. At the same time, assign the service name to the property Name of the Extern Bitmap object existing in the item.
I hope it provides the desired functionality.
Best regards
Paul Banach
