Hi Adeel Arif,
IComment object has a function getCreationDate(); that will allow you to show the creation date. You can sort the list of comments and get the latest one.
If you want to display the latest created comment of the Master mode of a ContentView based control you have to create a custom class that ionherits from the ContentView based control, map the templates, add label to the master template that will show the latest comment name and date or whatever you want.
In you custom class override SetItemContent where you have access to the id of each content item by using "contentItem" parameter of the method. This will allow you to get the comments for your content item object.
