posted

Hi,

i have a problem with the timeline.

in my modell i have a property:

        public DateTime SelectedTime
        {
            get
            {
                return _selectedTime;
            }
 
            set
            {
                if (_selectedTime != value)
                {
                    _selectedTime = value;
                    ParameterChanged = true;
                    NotifyPropertyChanged("SelectedTime");                    
                }
            }
        }

Now i wantto bind this to the timeline so i have the selected timeline DateTime in my modell.

<ig:DateTimeAxis Minimum="{Binding MinTime}" Maximum="{Binding MaxTime}" SelectedTime="{Binding SelectedTime}" 
                 ShowThumb="False" ShowMinorGridLines="False" ShowMinorTickMarks="True"  />

    Hello Steffen,

     

    I have been looking into your issue and it appears that the SelectedTime property’s value is being set internally to provide the selection functionality which overrides the TwoWay Binding. In order to overcome this a custom DateTimAxis can be created that would have a new property used only for binding. I have created a sample project for you that demonstrates all that (TimeLine_custom_proeprty.zip)

     

    Please let me know if I can be of any further assistance on the matter whatsoever.

    EDIT:
    if i choose

    SelectedTime="{Binding SelectedTime, Mode=OneWayToSource}"

    the source refreshes but no selection is shown on timeline!
    With 2-Ways nothings happens.

    :(
