WPF中实现PropertyGrid的三种方式
2010-10-09 08:16:11 来源:WEB开发网代码如下:
代码
using System.Activities.Presentation;
using System.Activities.Presentation.Model;
using System.Activities.Presentation.View;
using System.Reflection;
using System.Windows.Controls;
namespace System.Windows.Control
{
/// <summary>
/// WPF Native PropertyGrid class, taken from Workflow Foundation Designer
/// </summary>
public class WpfPropertyGrid : Grid
{
#region Private fields
private WorkflowDesigner Designer;
private MethodInfo RefreshMethod;
private MethodInfo OnSelectionChangedMethod;
private TextBlock SelectionTypeLabel;
private object TheSelectedObject = null;
#endregion
#region Public properties
/// <summary>
/// Get or sets the selected object. Can be null.
/// </summary>
public object SelectedObject
{
get
{
return this.TheSelectedObject;
}
set
{
this.TheSelectedObject = value;
if (value != null)
{
var context = new EditingContext();
var mtm = new ModelTreeManager(context);
mtm.Load(value);
var selection = Selection.Select(context, mtm.Root);
OnSelectionChangedMethod.Invoke(Designer.PropertyInspectorView, new object[] { selection });
this.SelectionTypeLabel.Text = value.GetType().Name;
}
else
{
OnSelectionChangedMethod.Invoke(Designer.PropertyInspectorView, new object[] { null });
this.SelectionTypeLabel.Text = string.Empty;
}
}
}
/// <summary>
/// XAML information with PropertyGrid's font and color information
/// </summary>
/// <seealso>Documentation for WorkflowDesigner.PropertyInspectorFontAndColorData</seealso>
public string FontAndColorData
{
set
{
Designer.PropertyInspectorFontAndColorData = value;
}
}
#endregion
/// <summary>
/// Default constructor, creates a hidden designer view and a property inspector
/// </summary>
public WpfPropertyGrid()
{
this.Designer = new WorkflowDesigner();
var inspector = Designer.PropertyInspectorView;
Type inspectorType = inspector.GetType();
inspector.Visibility = Visibility.Visible;
this.Children.Add(inspector);
var methods = inspectorType.GetMethods(Reflection.BindingFlags.Public | Reflection.BindingFlags.NonPublic | Reflection.BindingFlags.Instance |
Reflection.BindingFlags.DeclaredOnly);
this.RefreshMethod = inspectorType.GetMethod("RefreshPropertyList",
Reflection.BindingFlags.NonPublic | Reflection.BindingFlags.Instance | Reflection.BindingFlags.DeclaredOnly);
this.OnSelectionChangedMethod = inspectorType.GetMethod("OnSelectionChanged",
Reflection.BindingFlags.Public | Reflection.BindingFlags.Instance | Reflection.BindingFlags.DeclaredOnly);
this.SelectionTypeLabel = inspectorType.GetMethod("get_SelectionTypeLabel",
Reflection.BindingFlags.Public | Reflection.BindingFlags.NonPublic | Reflection.BindingFlags.Instance |
Reflection.BindingFlags.DeclaredOnly).Invoke(inspector, new object[0]) as TextBlock;
this.SelectionTypeLabel.Text = string.Empty;
}
/// <summary>
/// Updates the PropertyGrid's properties
/// </summary>
public void RefreshPropertyList()
{
RefreshMethod.Invoke(Designer.PropertyInspectorView, new object[] { false });
}
}
}
效果:
总结:
