PropertyGrid : Remove properties at runtime

[ZejulioZ]

Hi, I've some issues using property grid features, more specifically removing properties from the propertyGrid's selected object. I want to edit the properties of the class at runtime, and dynamically remove some of them depending on some criteria. The attribute [Browsable(false)] does not do what I need since it does not allow me to dynamically select what to remove, and invoking Properties.Remove in the component.PreFilterProperties method is more what I'm looking for. Unfortunately, and contrary to all the msdn's articles I've read on the subject, what I'm doing is not working as expected. Here is a snippet to illustrate my point : -------------------------------- entity = new Entity(); entity.MyValue = "Hello world !"; propertyGrid1.SelectedObject = entity; [Designer(typeof(Entity.EntityDesigner))] public class Entity : Component { public Entity() { } private string myValue; public string MyValue { set { myValue = value; } get { return myValue; } } public class EntityDesigner : Component { public EntityDesigner() { } protected override void PreFilterProperties( IDictionary Properties ) { base.PreFilterProperties( Properties ); Properties.Remove("MyValue"); } } } -------------------------------- The 'entity' class is never instantiated, and I suspect this is because it will only be done at design-time and not runtime, could you confirm this ? Or am I missing something else ? Thanks for the help, Julien

Oups sorry about that, propertyGrid1 is a System.Windows.Forms.PropertyGrid control.
