lo he hecho siguiendo this code en el pasado:
class DictionaryPropertyGridAdapter : ICustomTypeDescriptor
{
IDictionary _dictionary;
public DictionaryPropertyGridAdapter(IDictionary d)
{
_dictionary = d;
}
public string GetComponentName()
{
return TypeDescriptor.GetComponentName(this, true);
}
public EventDescriptor GetDefaultEvent()
{
return TypeDescriptor.GetDefaultEvent(this, true);
}
public string GetClassName()
{
return TypeDescriptor.GetClassName(this, true);
}
public EventDescriptorCollection GetEvents(Attribute[] attributes)
{
return TypeDescriptor.GetEvents(this, attributes, true);
}
EventDescriptorCollection System.ComponentModel.ICustomTypeDescriptor.GetEvents()
{
return TypeDescriptor.GetEvents(this, true);
}
public TypeConverter GetConverter()
{
return TypeDescriptor.GetConverter(this, true);
}
public object GetPropertyOwner(PropertyDescriptor pd)
{
return _dictionary;
}
public AttributeCollection GetAttributes()
{
return TypeDescriptor.GetAttributes(this, true);
}
public object GetEditor(Type editorBaseType)
{
return TypeDescriptor.GetEditor(this, editorBaseType, true);
}
public PropertyDescriptor GetDefaultProperty()
{
return null;
}
PropertyDescriptorCollection
System.ComponentModel.ICustomTypeDescriptor.GetProperties()
{
return ((ICustomTypeDescriptor)this).GetProperties(new Attribute[0]);
}
public PropertyDescriptorCollection GetProperties(Attribute[] attributes)
{
ArrayList properties = new ArrayList();
foreach (DictionaryEntry e in _dictionary)
{
properties.Add(new DictionaryPropertyDescriptor(_dictionary, e.Key));
}
PropertyDescriptor[] props =
(PropertyDescriptor[])properties.ToArray(typeof(PropertyDescriptor));
return new PropertyDescriptorCollection(props);
}
}
class DictionaryPropertyDescriptor : PropertyDescriptor
{
IDictionary _dictionary;
object _key;
internal DictionaryPropertyDescriptor(IDictionary d, object key)
: base(key.ToString(), null)
{
_dictionary = d;
_key = key;
}
public override Type PropertyType
{
get { return _dictionary[_key].GetType(); }
}
public override void SetValue(object component, object value)
{
_dictionary[_key] = value;
}
public override object GetValue(object component)
{
return _dictionary[_key];
}
public override bool IsReadOnly
{
get { return false; }
}
public override Type ComponentType
{
get { return null; }
}
public override bool CanResetValue(object component)
{
return false;
}
public override void ResetValue(object component)
{
}
public override bool ShouldSerializeValue(object component)
{
return false;
}
}
private void Form1_Load(object sender, System.EventArgs e)
{
IDictionary d = new Hashtable();
d["Hello"] = "World";
d["Meaning"] = 42;
d["Shade"] = Color.ForestGreen;
propertyGrid1.SelectedObject = new DictionaryPropertyGridAdapter(d);
}
funcionó bien para nosotros.
gracias amigo ! tu código es de mucha ayuda completa. –
