attached-properties

I can't get the following XAML to work as I want. All bindings work because get no errors from the bindings. But I don't get the expected result from the binding on the RatioShape rectangle. The problem is that the attached property wpflib:RatioPanel.Ratio always returns its default value, not the databound value. So I'm thinking that the attached property on RatioShape is set in the wrong "context". How do bind to the attached property so that wpflib:RatioPanel gets the bound value? <wpflib:RatioContentPresenter2 RatioMaxValue="{Binding Path=RatioMaxValue}"> <ItemsControl Grid.Row="0" wpflib

I've seen some really varying uses of AttachedProperties so far in my adventures in WPF, and am wondering, what are some of the various uses? I've seen fairly mundane uses, such as those found in Grid and Canvas, as well as some really cool hacks allowing binding to collections without setters. What other applications have you found for AttachedProperties? (Code samples really helpful!) Take a look into attached behaviours. http://www.codeproject.com/KB/WPF/AttachedBehaviors.aspx //not sure on the quality of this link. First one I came to after googling. Attaching a behavior to an object

I have created slightly customized vertical scrollbar for my DataGrid. In it I have added an ItemsControl to hold positions of the selected items. Here is a mockup so far with hard-coded markers. Below is my customized vertical scrollbar template where the ItemsControl is placed with hard-coded marker values. <ControlTemplate x:Key="VertScrollBar" TargetType="{x:Type ScrollBar}"> <Grid> <Grid.RowDefinitions> <RowDefinition MaxHeight="18" /> <RowDefinition Height="0.00001*" /> <RowDefinition MaxHeight="18" /> </Grid.RowDefinitions> <Border Grid.RowSpan="3" CornerRadius="2" Background="#F0F0F0"

My goal is to manipulate the text-styles of my application via DependencyProperties. I got a diagram in which the texts are to be manipulated in size, fontfamily, color, etc. So I'd like to use an interface similar to a rich text editor like Word. I'm using this code in my TextStyleVM http://shevaspace.blogspot.com/2006/12/i-have-some-fun-with-formattedtext_14.html So I have a FontFamilyProperty and a Getter and Setter for it: public static DependencyProperty FontFamilyProperty = DependencyProperty.Register( "FontFamily", typeof(FontFamily), typeof(OutlinedText), new FrameworkPropertyMetadata(

I have the following code: this.Object.GetType().GetProperty(this.PropertyName).GetValue(this.Object, null); PropertyName is a string, containing the name of the property I want to get. This works fine for "normal" properties, but I can't get the "Canvas.LeftProperty" or "Canvas.TopProperty". Can anyone help me out? Thanks, Chris I think this is because Canvas.Left is attached property and to retrieve them try this: private DependencyProperty GetAttachedProperty(DependencyObject obj, string propertyName, Type ownerType) { foreach (PropertyDescriptor pd in TypeDescriptor.GetProperties(obj, new

I'm trying to bind from Button's ContentTemplate to attached property. I read all the answers for question similar to "binding to attached property" but I had no luck resolving the problem. Please note that example presented here is a dumbed down version of my problem to avoid cluttering the problem with business code. So, I do have static class with attached property: using System.Windows; namespace AttachedPropertyTest { public static class Extender { public static readonly DependencyProperty AttachedTextProperty = DependencyProperty.RegisterAttached( "AttachedText", typeof(string), typeof

I am trying to use an Image in Button Control which animates on Hover and Pressed state by showing different images. Accordingly, I have defined 3 attached properties for the Button Control as given below. public class ButtonExtensions : DependencyObject { public static DependencyProperty ImageSourceProperty = ... public static DependencyProperty ImageHoverSourceProperty = ... public static DependencyProperty ImagePressedSourceProperty = DependencyProperty.RegisterAttached("ImagePressedSource", typeof(string), typeof(ButtonExtensions)); public static string GetImagePressedSource(Button target)
