Why is the update strategy not preferred to be used in DataGrid control?

- The update strategy is inefficient to provide the updates to the database for each of the grid row.

- The updates sent are not sufficient to show the changes that are being made every minute/seconds.

- Manual logic needs to be updated to check for the changes that has taken place between the controls in a particular row in grid.

- Comparisons are hard to make between different datasets and databases that involves a round trip.

- No checking of the database take place to see the updations and changes made in it after some time.
