I'm writing an app in WPF, trying to use the MVVM-design pattern (which is new to me).

bound to an ObservableCollection
.
Delete the currently selected DataGrid-row using a 'Delete'-button. I've tried a plethora of forum-posts and videos to find a solution. The solution has probably stared me right in the face several times, but at this point I'm more confused than I was when I first started.
Any assistance would be appreciated.

I'm attempting to pass my ID variable to my edit function so I can POST my changes to my database. However, I'm receiving this error...

and you're passing variable item
as your parameter. But in your template there is no such thing defined - I assume (without looking at the rest of your code) that you wanted to write editData(forecast)
instead. This will pass the forecast
variable defined in your *ngFor
directive.

I have an excel file with about 21000 rows . I imported it into a temp Table in my database.
Now I want to do some conversions on my data and then put them into my main table.
When I do SaveChanges()

Microsoft.Data.SqlClient.SqlException: 'New transaction is not allowed because there are other threads running in the session
When I use it after the foreach
no error occurs and the table has just 4 records inserted instead of all 21000 records that I expected.

.
Don't just surround every value in any SQL you ever write, with ''
