Hi my friends, I have been practicing with the project and I have managed to integrate several components such as:
- Add items (success)
- Edit items (success)
- Filter Items (success)
- Sort columns (success)
- Save and open data (error)
All codes I use are from the friend "getmem"
please help me, how can I save and open without error
PD: attached images and Project.
the rarest thing is that save and open works while not closing the application, if I close the application no longer opens.
