I don't know how much thanks I owe ya for this video, I noticed you have been updating the video even though keeping the title the same, this video has finally resolved my doubts about linking two data tables using entity framework and display it on a datagridview, job well done, I really owe you a beer! Cheers!

Good hands on tutorial. Everyone commenting here asked for source code. wow

This Database I'm downloading (The up-to-date version of what you got);
does it allow connections over the internet? Let's say I'm making a social app,
how would I handle that kind of data between everyone? This type of Database?

One more question, is there a way to save the cityid each time I enter into the edit screen? seems like it always defaulted to the first item, many thanks!

Very Good work!

I have some questions...

- After deleting a row, dataGridView does't update automatically.
I must press the sequence:
1. Delete
2. Save
3. Refresh
Doesn't better to call SaveChangesAsync() right after delete?

- Why after the sqeuence:
1. Delete
2. SaveChangesAsync()
I need press Refresh button? (the dataGridView doesn't refresh automatically)

Sorry for my english.

Thanks

Once I'm on the Student Info dialog box that I click on the address text box, the name on the city combo box disappears and when you select it doesn't let you save the record, no errors occur. Please help. thaks

Hi! This tutorial is very good and really helpful. One question regarding editing. When you add a record, everything is ok with ComboBox data (you choose a city and its ID gets written into the record).
But when you edit a record, ComboBox is not initialized with correct value from the DB, but rather set to its default value (as if you are creating a new record). What is the best practice to solve this (ComboBox being set to its correct value from the DB record when editing a record)?
Many tnx for the answer.

BR, Smiljan

When I go to edit form... City not initial correct always get first value. and when you choose edit row you choose row not have city .. How can I initial City value... Thank you

mrkhedr

Very nice video that explains a lot! However I wanted to ask you if you begin editing a row and change one or two fields and then close the edit dialog without saving, the underlying data in binding context would have changed.Correct? And hence those data would have been displayed in the grid but not persisted in database. Is my assumption correct?
Also could you send me the source code?
Thanks again for the great video!
