[英]How to create a custom property editor for Extended WPF Toolkit PropertyGrid with another (nested) editor in C#?
我有以下通用類:
public class Member<T>
{
public bool IsDirty { get; set; }
public T Value { get; set; }
}
我想為PropertyGrid創建一個自定義編輯器,它允許我通過CheckBox
編輯IsDirty
屬性,並通過另一個嵌套編輯器編輯Value
屬性。
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;
}
}
現在我正在尋找一種方法來替換 TextBox,例如:
// ...
TEditor editorResolver;
PropertyItem innerPropertyItem;
// ... magic happens here ...
FrameworkElement valueEditor = editorResolver.ResolveEditor(innerPropertyItem);
// ...
主要目標是避免為每個嵌套的編輯器類型創建新類。
任何想法將不勝感激!
看看我在這個SO question 中提供的解決方案,我通過一個按鈕和一個單獨的窗口提供了一個自定義編輯器。
