Hi!
I have the following situation: there is a table in the DB that is queried when the form loads and the retrieved data is filled into a DataGridView via the DataTable underneath. After the data is loaded the user is free to modify the data (add / delete rows, modify entries).
The form has 2 buttons: Apply and Refresh. The first one sends the changes to the database, the second one re-reads the data from the DB and erases any changes that have been made by the user.
My question is: is this the best way to keep a DataGridView synchronized with the DB (from a users point of view)?
For now these are the downsides:
- the user must keep track of what he is doing and must press the button every while
- the modifications are lost if the form is closed / app crash / ...
I tried sending the changes to the DB on CellEndEdit event but then the user also needs some Undo/Redo functionality and that is ... well ... a different story.
So, any suggestions?
