Problem Binding to a Brush Property in WPF
- by Krisc
Working in WPF, writing a custom user control. I am trying to change the background property of the Border element when I change the value of a property of the class. Right now I am working on simply binding it to a DP, though if there is a better way I am open to suggestions.
Here is the XAML for the UserControl
<UserControl x:Class="MyProject.MyControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:js="clr-namespace:MyProject"
mc:Ignorable="d"
x:Name="MyControlRootLayout"
Background="Transparent"
d:DesignHeight="300" d:DesignWidth="300" Cursor="Hand">
<Border x:Name="RootBorder"
Background="{Binding Path=CoreBackground, ElementName=MyControlRootLayout}"
>
</Border>
</UserControl>
And the code...
public partial class MyControl : UserControl
{
public static DependencyProperty IsSelectedProperty = DependencyProperty.Register("IsSelected", typeof(bool), typeof(MyControl));
public static DependencyProperty CoreBackgroundProperty = DependencyProperty.Register("CoreBackground", typeof(Brush), typeof(MyControl));
public MyControl()
{
CoreBackground = new SolidColorBrush(Color.FromArgb(0, 255, 245, 104));
InitializeComponent();
Margin = new Thickness(5);
}
public Brush CoreBackground
{
get { return (Brush)GetValue(CoreBackgroundProperty); }
set { SetValue(CoreBackgroundProperty, value); }
}
public bool IsSelected
{
get { return (bool)GetValue(IsSelectedProperty); }
private set { SetValue(IsSelectedProperty, value); }
}
}
Instead, the background comes out as transparent.
