Hello Sam,
Setting the EditControl.ContextMenuEnabled property to false value does disable the context menu and the hot keys that get activated are associated with the editcontrol itself. And so if you want to disable the hot keys such as Ctrl +P and etc., you need to remove the corresponding key binding using the EditControl.KeyBinder.RemoveBinding(..) method. Below is the sample code snippet for your reference.
this.editControl1.KeyBinder.RemoveBinding(Keys.Control | Keys.F);
this.editControl1.KeyBinder.RemoveBinding(Keys.Control | Keys.P);
this.editControl1.KeyBinder.RemoveBinding(Keys.Control | Keys.H);
Please try with the above details and let me know if you have any questions.
Best Regards,
Meera.
