Thank you for writing.
I can confirm that the SelectionChanging/Changed events are not being fired in the described scenario, however the amount of SelectedRows is properly updated. You can see that by running a Timer which every few milliseconds writes the amount of selected rows to the console. I have logged the issue here: UI for Winforms Feedback Portal - FIX. RadGridView does not fire the SelectionChanging event when a selected cell is clicked with Ctrl being held
As a workaround, you can subscribe to the PropertyChanging event of each row:
.Grid.Rows.ToList().ForEach(x => x.PropertyChanging += x_PropertyChanging);
sender, Telerik.WinControls.Interfaces.PropertyChangingEventArgsEx e)
I have updated your Telerik Points
for reporting this.
Do not hesitate to let me know, should you have further questions.
