Note: This is continuation of my previous article Part 2. Please click here to go to Part 2
In this Part 3, we will enhance our Listing and model window as follows
1. We will include one more column as last named as Actions. This action will contain image such as edit, activate and delete.
2. We will also give hyperlink for the first column. If the user clicks the first column, then we will show the information in the read-only and if the user clicks the edit image in the action column, then we will show the information in the read only and will allow the user to edit and save.
