Question

What is the UITypeEditor for ToolStrip.Items?

Answer 1

+1 A:

Looks like it is System.Windows.Forms.Design.ToolStripCollectionEditor internal class from the System.Design assembly:

[Editor("System.Windows.Forms.Design.ToolStripCollectionEditor, System.Design, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a", typeof(UITypeEditor))]
public class ToolStripItemCollection : ArrangedElementCollection, IList, ICollection, IEnumerable
{
...
}

Thanks very much! I'm guessing its internal state means I cannot use it on a Property...

I think you should try :) You cannot directly instantiate (or derive from) this internal class in you code, but .NET Framework itself can do it.

When I open the editor I get an error message ("Value cannot be null. Parameter name: value") and the editor does not open. The collection wouldn't be null because it references an existing ToolStrip. Have you come across this message before? Thanks

Got same message. Debugged and looked at the code causing an exception with Reflector. Unfortunately ToolStripCollectionEditor explicitly assumes that only ToolStrip should be the owner of property with ToolStripItemCollection type. It seems there is no good workaround.

Thanks for you time :)

@Tony, you should use reflector to decompile the editor then create your editor based on it.
