I have a appointment system just like uploaded image. I want to when when pulled down from the appointment block, changing block height and update to database. Appointment block architecture: Grid > Border > Textblock
If I understand your problem correctly, you essentially want to be able to alter the duration of the appointments in your calendar by using a drag feature. So if a specific appointment is dragged down you want this drag to be reflected visually and also change the properties of the appointment in the database.
I think I am your guy for this problem. I have work experience as a data scientist so I am extremely proficient at back end development. I am adept at moving data through databases and setting up pipelines to ensure fluid flows of data and I eat SQL server for breakfast.
My previous experience has been with developing a wpf application that enabled the management of data for a small record label accounting firm. I have also conducted many personal projects involving c# and eager for more real world development exposure.
