    text
    copied!<p>My problem is certainly right on my face but I can't see it...</p> <p>I am building a very simple user control - a 3D ellipse - and I expose two properties: LightColor and DarkColor. I need to bind these properties to the gradient in my user control, but it is not showing any color at all. Here's my usercontrol:</p> <pre><code>&lt;UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:local="clr-namespace:TestBrushes" mc:Ignorable="d" x:Class="TestBrushes._3DEllipse" x:Name="UserControl" d:DesignWidth="200" d:DesignHeight="200"&gt; &lt;Grid x:Name="LayoutRoot"&gt; &lt;Ellipse Name="MainEllipse" Stroke="{x:Null}"&gt; &lt;Ellipse.Fill&gt; &lt;RadialGradientBrush GradientOrigin="0.5,1.1"&gt; &lt;GradientStop Color="{Binding ElementName=UserControl, Path=LightColor}" Offset="1"/&gt; &lt;GradientStop Color="{Binding ElementName=UserControl, Path=DarkColor}" Offset="0"/&gt; &lt;/RadialGradientBrush&gt; &lt;/Ellipse.Fill&gt; &lt;/Ellipse&gt; &lt;Ellipse Name="TopReflectionEllipse" Stroke="{x:Null}" Margin="38,0,38,0" VerticalAlignment="Top" Height="90"&gt; &lt;Ellipse.Fill&gt; &lt;RadialGradientBrush GradientOrigin="0.5,0"&gt; &lt;RadialGradientBrush.RelativeTransform&gt; &lt;TransformGroup&gt; &lt;ScaleTransform CenterX="0.5" CenterY="0.5" ScaleX="1" ScaleY="1"/&gt; &lt;SkewTransform AngleX="0" AngleY="0" CenterX="0.5" CenterY="0.5"/&gt; &lt;RotateTransform Angle="0" CenterX="0.5" CenterY="0.5"/&gt; &lt;TranslateTransform X="0" Y="0"/&gt; &lt;/TransformGroup&gt; &lt;/RadialGradientBrush.RelativeTransform&gt; &lt;GradientStop Color="#A5FFFFFF" Offset="0"/&gt; &lt;GradientStop Color="#00FFFFFF" Offset="1"/&gt; &lt;/RadialGradientBrush&gt; &lt;/Ellipse.Fill&gt; &lt;/Ellipse&gt; &lt;/Grid&gt; &lt;/UserControl&gt; </code></pre> <p>and here's my code-behind:</p> <pre><code>public partial class _3DEllipse { public _3DEllipse() { InitializeComponent(); } public Color DarkColor { get; set; } public Color LightColor { get; set; } } </code></pre> <p>If I assign colors as opposed to the binding shown in the code, it works ok, but I want to use the properties I am exposing. What am I doing wrong?</p> <p>Thanks!</p>
