Show all the System.Windows.Media.Colors using DataBinding

jobi — Thu, 01 Nov 2007 19:17:00 GMT

Here is a sample to show all the Colors or even Brushes of WPF System.Windows.Media.Colors class.

<ListBox ItemsSource="{Binding Mode=OneWay, Source={StaticResource helper}}" ItemTemplate="{DynamicResource DataTemplate1}"/>

Bellow is a function which gives all of its properties as PropertyInfo Collection.(If anybody out here knows a way to eliminate the use of this Helper class, please point that here)

public class Helper{ public PropertyInfo[] GetPropNames(Type type) { return type.GetProperties(); }}

Now you can write an ObjectDataProvider in XAML to call this function and then a DataTemplate to bind the PropertyName to the approapriate Dependancy Property. See the XAML

<Window.Resources> <ObjectDataProvider x:Key="helper" MethodName="GetPropNames" ObjectType="{x:Type local:Helper}"> <ObjectDataProvider.MethodParameters> <x:Type TypeName="Colors"/> </ObjectDataProvider.MethodParameters> </ObjectDataProvider> <DataTemplate x:Key="DataTemplate1"> <StackPanel Orientation="Horizontal"> <Rectangle Width="40" Height="28" Fill="{Binding Name}" Stroke="#FF000000"/> <TextBlock Text ="{Binding Name}" Foreground="{Binding Name}" /> </StackPanel> </DataTemplate> </Window.Resources>

Now if you need to show Brushes class members just need to replace Colors from the XAML with Brushes as shown here

<ObjectDataProvider x:Key="helper" MethodName="GetPropNames" ObjectType="{x:Type local:Helper}"> <ObjectDataProvider.MethodParameters> <x:Type TypeName="Brushes"/> </ObjectDataProvider.MethodParameters> </ObjectDataProvider>
