This would seem to indicate that the new BindingSource was resetting the values. While it may not be a bug, it's certainly not a very clever API design (by the designers of WinForms, not you I will hasten to add).
Okay, I've been having more of a think about this and I suspect that the reason that you need to do this is because when you change your BindingSource, the ComboBox has no concept of what it's bound to. You could be binding to something that doesn't use Key and Value here, so it forces you to update these values here.

Short Story: I'm a Newbie in application security. I need to implement a login via email.
Long Story: I have built a basic web chat application using SignalR, now i'm working in saving conversation in SQLServer Db. But my next challenge is to create a chat invitation email that will be send to all users from my db. The email should contain a link that when users will click they will be redirected to the chat web-page and automatically signed in.
My question is: Can it be done? And if it can, how can it be done
Thank you for your help!

A very insecure method to be actually implemented in an applicaton (or in any application).
But, yes, if you want to login the users automatically. Then you can create a URL that redirects the user to such a page where the UserName and the Password would be automatically set to login the user.
Tip: Instead of using a username/password there, you can use a token generated by the user each time he sends the email to others.

I have a DataGridView with local database and identity, i want identity without hyphen how dow i that?
|
|
|
|

Identity? Hyphen? What hyphen??
Again, you provide absolutely no context to your question.

When you ask a question, you need to consider your audience. We don't know what's on your screen. What are your inputs? What output are you expecting? What are the rules to do the processing?

I'm out. I've asked so many times for exactly what you're doing and you have failed to answer those questions time and time again.
You're on your own.

IMO, if this is how you behave, he should take it as a blessing that you are no longer involving yourself.
I suggest that you use your intelligence to take a look at your behaviour, and seek out "syntax changes" that will make it functional.
BTW, this is not a discussion. I have said what needed to be said, and will not visit this thread again.

When you write your insert statement, don't attempt to insert a value into the fields that have identities set. Identities are automatically created for you by the database server. If you want to get the value that you created back, you simply use
SELECT Scope_Identity() AS CreatedIdentity immediately after the insert.

I know I shouldn't, but I just had to upvote that.

Hell I shouldn't of even posted it! But, I only have so much patience and I've tried asking him for more detail so many times and gotten nothing but a blank stare back.

I think It is using GUIDs as the identity column.
GUIDS have hyphens and I 'ont whant no mur hypens.
|
|
|
|

Actually GUIDs have no hyphens (these are numbers after all), it just happened that we mostly display it such way to help our eyes...

But, when you query the DB (SQL Server) you get a value back for your (uniqueidentifier) identity which looks like:
BF5B2C5A-8E79-4FA0-8510-B3FD6BC819D6 (uniqueidentifier)
Right? So if you then try to do something with that value you would have hyphens and I was thinking that is what was hanging him up?
|
|
|
|
|
Yes, SQL - and others too - turn GUID into string...
If you read the RFC[^] you will understand why, but after all GUID is a 128 bit number...

Agree 100%.
Was just speaking about hyphens in this case with Guid identities in SQL.
