Cancel key pressing

[Josep]

Hi folks,

I need cancel any keyboard input pressing on schedule view (specially Del key). I have tested:

                    <schedule:SfSchedule x:Name="schedule" Grid.Column="0" Grid.Row="0"
                        CurrentDateBackground="DarkCyan"
                        CurrentDateForeground="White"
                        CellSelectionBrush="DarkBlue"
                        ScheduleType="Month"
                        ScheduleClick="schedule_ScheduleClick"
                        PreviewKeyDown="schedule_PreviewKeyDown"/>


        private void schedule_PreviewKeyDown(object sender, KeyEventArgs e)
        {
            e.Handled = false;
        }

But Del que still deletes appointments (I do not want to delete using keyboard)

Cheers

Hi Josep 

 

Thanks for your patience. 

 

As of now we don’t have any direct support to prevent deleting appointment when Delete key pressed. But we have created a sample level workaround to achieve your requirement by using AppointmentCollectionChanged event. Please find the sample in the below link. 

 

Sample link:
SfSchedule_WPF
 

 

In the above sample based on the NotifyCollectionChangedAction we have achieved your requirement. Please find the below code snippet for the same. 

 

private void Schedule_AppointmentCollectionChanged(object sender, System.Collections.Specialized.NotifyCollectionChangedEventArgs e) 

        { 

            if (e.Action == NotifyCollectionChangedAction.Remove && this.isDeleteButtonPressed) 

            { 

 

            } 

        } 

 

Please let us know if you have any concern. 

 

Regards
