QuestionDataGrid with DataGridTemplateColumns - Cannot create new rows Pin
Mc_Topaz7-Oct-19 23:42
MemberMc_Topaz7-Oct-19 23:42 
I have a DataGrid with a couple of DataGridTemplateColumns.
When I try to hit the Enter-key on my keyboard there is no new row created in the DataGrid.

I have other DataGrids with columns which are not DataGridTemplateColumns and I can then create new rows by hitting the Enter-key. So I assume the DataGridTemplateColumns in some way causing the problem.

I have made a reproducible code and I have made it public in this GIT-Gist.
* I use Fody PropertyChanged to handle all the INotificationPropertyChanged in my view models.
* The code should just be copy-and-paste.

The bindings between the View and the ViewModels also don't seem to work :S
But if you uncomment the row in the ViewModel's construcotor (please see line 60 in the MainWindow.xaml.cs), a new row in the DataGrid will be created. With this row, the bindings works as expected. I cannot understand why.

Here is the XAML-code. It maybe enough for you with only the XAML-code to solve this problem.
