How to create a custom property editor for Extended WPF Toolkit PropertyGrid with another (nested) editor in C#?
提问by zaantar
I have following generic class:
我有以下通用类：
public class Member<T>
{
public bool IsDirty { get; set; }
public T Value { get; set; }
}
I want to create a custom editor for the PropertyGridthat will allow me to edit the IsDirtyproperty through a CheckBoxand the Valueproperty through another nested editor.
我想为PropertyGrid创建一个自定义编辑器，它允许我IsDirty通过 a编辑属性，CheckBox并Value通过另一个嵌套编辑器编辑属性。
With help I found hereI've got this far:
class MemberEditor<T, TEditor> : ITypeEditor where TEditor : ITypeEditor
{
public FrameworkElement ResolveEditor(PropertyItem propertyItem)
{
//var member = propertyItem.Value as Member<T>;
// checkbox for the Member.IsDirty value
var isDirtyCheckbox = new CheckBox();
var isDirtyBinding = new Binding("Value.IsDirty");
isDirtyBinding.Source = propertyItem;
isDirtyBinding.ValidatesOnDataErrors = true;
isDirtyBinding.ValidatesOnExceptions = true;
isDirtyBinding.Mode = BindingMode.TwoWay;
BindingOperations.SetBinding(isDirtyCheckbox, CheckBox.IsCheckedProperty, isDirtyBinding);
// inner editor
var valueEditor = new TextBox();
var valueBinding = new Binding("Value.Value");
valueBinding.Source = propertyItem;
valueBinding.ValidatesOnExceptions = true;
valueBinding.ValidatesOnDataErrors = true;
valueBinding.Mode = BindingMode.TwoWay;
BindingOperations.SetBinding(valueEditor, TextBox.TextProperty, valueBinding);
// compose the editor
var dockPanel = new DockPanel();
DockPanel.SetDock(isDirtyCheckbox, Dock.Left);
dockPanel.Children.Add(isDirtyCheckbox);
DockPanel.SetDock(valueEditor, Dock.Right);
dockPanel.Children.Add(valueEditor);
return dockPanel;
}
}
Now I am looking for a way to replace the TextBox, for something like this:
现在我正在寻找一种方法来替换文本框，如下所示：
// ...
TEditor editorResolver;
PropertyItem innerPropertyItem;
// ... magic happens here ...
FrameworkElement valueEditor = editorResolver.ResolveEditor(innerPropertyItem);
// ...
The main goal is to avoid creating new class for each nested editor type.
主要目标是避免为每个嵌套的编辑器类型创建新类。
Any ideas will be very much appreciated!
任何想法将不胜感激！

Take a look at the solution that I provided in this SO question, where I provide a custom editor via a button and a separate window.
看看我在这个SO question 中提供的解决方案，我通过一个按钮和一个单独的窗口提供了一个自定义编辑器。
