New Post: PropertyGrid custom type error

Hi,

I would replace

<TextBlock  Background="{Binding Value.Brush}" />

width

<TextBlock  Background="{Binding Value}" />

in order to see the TextBlock Background color.


You can always replace

<xctk:TargetPropertyType Type="{x:Type local:myType}" />

with

<xctk:TargetPropertyType Type="Brush" />

to target a property name instead of property type.

But in your case, you are defining a DataTemplate for all property of type "myType", which is not a PropertyType, but a class type.
You should use :

<xctk:TargetPropertyType Type="{x:Type Brush}" />

So that all properties of type "Brush" will use your DataTemplate.

Complete Sample :

<Grid>
      <xctk:PropertyGrid x:Name="_propertyGrid"
                         SelectedObject="{Binding}">
         <xctk:PropertyGrid.EditorDefinitions>
            <xctk:EditorTemplateDefinition>
               <xctk:EditorTemplateDefinition.TargetProperties>
                  <xctk:TargetPropertyType Type="{x:Type Brush}" />
               </xctk:EditorTemplateDefinition.TargetProperties>
               <xctk:EditorTemplateDefinition.EditingTemplate>
                  <DataTemplate>
                     <Grid VerticalAlignment="Center"
                           HorizontalAlignment="Stretch">
                        <Grid.ColumnDefinitions>
                           <ColumnDefinition Width="*" />
                           <ColumnDefinition Width="Auto" />
                        </Grid.ColumnDefinitions>
                        <TextBlock  Background="{Binding Value}" />
                        <Button Grid.Column="1"
                                Content=". . ." />
                     </Grid>
                  </DataTemplate>
               </xctk:EditorTemplateDefinition.EditingTemplate>
            </xctk:EditorTemplateDefinition>
         </xctk:PropertyGrid.EditorDefinitions>
      </xctk:PropertyGrid>
    </Grid>

 public partial class MainWindow : Window
  {
    public MainWindow()
    {
      InitializeComponent();

      this.DataContext = new myType() { Name = "Mike", Age = 30, Brush = Brushes.Green };
    }
  }

  public class myType : DependencyObject
  {
    public string Name
    {
      get;
      set;
    }

    public int Age
    {
      get;
      set;
    }

    public static readonly DependencyProperty BrushProperty = DependencyProperty.Register( "Brush", typeof( Brush ), typeof( myType ) );
    public Brush Brush
    {
      get
      {
        return ( Brush )GetValue( BrushProperty );
      }
      set
      {
        SetValue( BrushProperty, value );
      }
    }
  }
