我的ProgressBar不会更新

Question

No matter what I do my progress bar won't update.

My XAML:

<Grid Height="25">
    <Grid.Style>
        <Style TargetType="{x:Type Grid}">
            <Setter Property="Visibility" Value="Collapsed" />
            <!--EDITING HERE-->
            <Style.Triggers>
                <DataTrigger Binding="{Binding Path=PleaseWaitDialog, Mode=OneWay}"
                             Value="true">
                    <Setter Property="Visibility" Value="Visible" />
                </DataTrigger>
            </Style.Triggers>
        </Style>
    </Grid.Style>
    <ProgressBar Value="{Binding Path=Percent}" />
</Grid>

Then in the ViewModel:

private double _percent;
public double Percent
{
    get { return _percent; }
    set
    {
        SetProperty("Percent", () => false, () => _percent = value);
    }
}

Then I set the value with:

_profileService.ApplyProfile(_data, (s, d) => UpdateApplyProgress(s, d, pleaseWaitVm));

and the update is:

private void UpdateApplyProgress(string message, double percent, CUDialogVM dialogVm)
    {
        //Dispatcher.CurrentDispatcher.Invoke(DispatcherPriority.Normal, new Action(() => dialogVm.Progress = percent));

        dialogVm.Percent = percent;
    }

I tried it with the dispatcher and it still didn't work. I have also tried setting the value explicitly and nothing. Also I have checked in the debugger and the viewModel's Percent property is being set and the PropertyChangedEvent is being fired.

The SetPropertyMethod:

protected bool SetProperty<T>(string propertyName, Func<bool> areEqual, Func<T> setValue)
    {
        VerifyPropertyName(propertyName);

        if (!areEqual.Invoke())
        {
            setValue.Invoke();
            RaisePropertyChanged(propertyName);
            IsChanged = true;
        }

        return true;
    }

As per HB below my binding now is:

<ProgressBar Minimum="0" Maximum="100" Value="{Binding Percent}" />

Answer 1

The ProgressBar.Minimum and Maximum defaults are 0 and 1 , are your values in that range? If not change those properties accordingly.

Answer 2

Try that in your XAML:

 <ProgressBar Value="{Binding Path=Percent, UpdateSourceTrigger=PropertyChanged}" />

Moreover, the ProgressBar values have to be between 0 and 100!
