问题 I'd like to add a property which represents a collection of controls to a component and have a collection editor with which I can easily select the controls that belong to the collection. VS does almost what I want automatically with the following code: Private _controls As New List(Of Control) <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property SelectedControls() As List(Of Control) Get Return _controls End Get End Property I get the default

问题 I have a custom control which has a property of type Collection<System.Drawing.Point> . When I use CollectionEditor to edit this property, the CollectionEditor window shows "Object does not match target type." for the "X" and "Y" properties. But if I use System.Drawing.PointF instead, there's no failure. Can anyone please explain why this difference occurs? 回答1: The difference between Point and PointF lies indeed with PointConverter. Why this causes a problem is quite a long story, but at the

问题 I am using the generic propertygrid to edit values from several custom classes. Some of these classes have collections and I can open those collections without a problem in the Collection Editor without a problem. If the collection already contains objects I am able to select those objects and edit them on the right, but the the Add/Remove buttons are inactive. I know for some of these collections are going to need a custom editor as they are quite complicated-- but most of them are quite

问题 I have a class containing a collection property which I want to display and edit in a property grid: [EditorAttribute(typeof(System.ComponentModel.Design.CollectionEditor), typeof(System.Drawing.Design.UITypeEditor))] public List<SomeType> Textures { get { return m_collection; } set { m_collection = value; } } However, when I try to edit this collection with the CollectionEditor , set is never called; why is this and how can I fix it?

Is there any way to use a CollectionEditor outside of the property grid?

问题 I'm replacing my property grid with something that will allow me to customize my UI a bit better. I placed a button on my form that I hope when clicked would pop up a CollectionEditor and allow me to modify my code. When I was using the PropertyGrid, all I needed to do was add some attributes to the property pointing to my CollectionEditor and it worked. But how do I invoke the CollectionEditor manually? Thanks! 回答1: Found the answer here: http://www.devnewsgroups.net/windowsforms/t11948
