Xaml，在Slider中设置默认值

Question

我可以在滑块中设置默认值吗？ 示例我有一个介于10和100之间的范围滑块，当我在视图白色滑块上打开时，我希望有defulat 50

<Slider x:Name="TimeSlider" Minimum="0" Maximum="100"    Margin="8,16,8,0"
                        Value="{Binding WaitingTime, Mode=TwoWay}"/>

ViewModel

private double _waitingTime = 0.1;
    public double WaitingTime
    {
        get => _waitingTime;
        set
        {
            _waitingTime = value;
            OnPropertyChanged();
        }
    }

...

private void ShareCommandExecute()
        {
            var waitingTime = Convert.ToInt32(WaitingTime);
            if(waitingTime > 0)
            {
                var customPinModel = new CustomPinModel
                {
                    WaitingTime = waitingTime * 1000,
                    CheckinExtrasType = (int)_checkinExtrasType
                };

                if(_pinPosition.Latitude == default(double) && _pinPosition.Longitude == default(double))
                {
                    GPSManagerInstance.Checkin(customPinModel);
                }
                else
                {
                    GPSManagerInstance.Checkin(customPinModel, _pinPosition);
                }

                CloseShareLayoutCommandExecute();
            }

您的滑块的值绑定到VM WaitingTime属性。如果您希望它默认为50，则应将WaitingTime的默认值设置为50。
