[QUOTE="sccrgoalie1, post: 1031145, member: 143879"] Hello, I'm slowly learning the new MP2 development and I'm having an issue with Binding that I can figure out. I know my model is bound correctly because when I set the property on first load it works just fine. The problem is when I try to update that property later nothing happens. Here's the relevant code: XAML [CODE=xml] <Grid x:Name="Picture1Grid" Margin="{Binding Path=Picture1GridMargin}"> <Grid.RenderTransform> <TransformGroup> <RotateTransform CenterX="100" CenterY="75" Angle="0" /> <ScaleTransform ScaleX="1" ScaleY="1"/> </TransformGroup> </Grid.RenderTransform> <Border x:Name="Picture1Border" BorderBrush="White" BorderThickness="10" MaxWidth="{Binding Path=Picture1Width}" MaxHeight="{Binding Path=Picture1Height}" HorizontalAlignment="Left" VerticalAlignment="Top" > <Image Source ="{Binding Path=Picture1}" Stretch="Uniform"/> </Border> <Label x:Name="Picture1Label" Content="{Binding Path=Picture1Date}" HorizontalAlignment="Center" VerticalAlignment="Bottom" Color="{Binding Path=Picture1DateColor}" FontSize="8"/> </Grid>[/CODE] CS [CODE=csharp] protected readonly AbstractProperty _picture1Property; protected readonly AbstractProperty _picture1GridMargin; protected readonly AbstractProperty _picture1Date; protected readonly AbstractProperty _picture1DateColor; protected readonly AbstractProperty _picture1Width; protected readonly AbstractProperty _picture1Height; public MPPhotoSlideshowModel() { try { // In models, properties will always be WProperty instances. When using SProperties for screen databinding, // the system might run into memory leaks. log = new Log(Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData) + @"\Team MediaPortal\MP2-Client\Log", "MPPhotoSlideshow", "log", LogType.Debug); _helloStringProperty = new WProperty(typeof(string), HELLOWORLD_RESOURCE); _picture1Property = new WProperty(typeof(object), null); _picture1Date = new WProperty(typeof(string), null); _picture1GridMargin = new WProperty(typeof(object), null); _picture1DateColor = new WProperty(typeof(object), null); _picture1Width = new WProperty(typeof(object), null); _picture1Height = new WProperty(typeof(object), null); LoadSettings(); LoadPage(); } catch (Exception ex) { if (log != null) { log.writeLog(ex.ToString(), LogInfoType.Error); } } } public string Picture1Date { get { return (string)_picture1Date.GetValue(); } set { _picture1Date.SetValue(value); } } public object Picture1 { get { return (object)_picture1Property.GetValue(); } set { _picture1Property.SetValue(value); } } public object Picture1GridMargin { get { return (object)_picture1GridMargin.GetValue(); } set { _picture1GridMargin.SetValue(value); } } public object Picture1DateColor { get { return (object)_picture1DateColor.GetValue(); } set { _picture1DateColor.SetValue(value); } } public object Picture1Height { get { return (object)_picture1Height.GetValue(); } set { _picture1Height.SetValue(value); } } public object Picture1Width { get { return (object)_picture1Width.GetValue(); } set { _picture1Width.SetValue(value); } } private void LoadPage() { try { PhotoTemplate template = _photoTemplates[_templateRnd.Next(_photoTemplates.Count)]; if (template.Photos[0].Enabled) { Picture picture1FileName; if (template.Photos[0].Image.Height > template.Photos[0].Image.Width) { picture1FileName = _verticalPictures[_verticalRnd.Next(_verticalPictures.Count)]; } else { picture1FileName = _horizontalPictures[_horizontalRnd.Next(_horizontalPictures.Count)]; } //log.writeLog(String.Format("MPSlideshow.LoadPage() - Setting new file name {0}",picture1FileName.FilePath), LogInfoType.Debug); Picture1 = picture1FileName.FilePath; Picture1GridMargin = String.Format("{0},{1},{2},{3}", template.Photos[0].Image.posX, template.Photos[0].Image.posY, 0, 0); Picture1Date = picture1FileName.DateTaken.ToString("d"); Picture1DateColor = template.Photos[0].Label.TextColor; Picture1Width = template.Photos[0].Image.Width; Picture1Height = template.Photos[0].Image.Height; } } catch (Exception ex) { log.writeLog(ex.ToString(), LogInfoType.Error); } }[/CODE] Any idea why this isn't updating.
