DictionaryBase / DictionaryEntry display in PropertyGrid control? Better way to display/edit a dictionary?

Question

Greetings,

My custom class contains several dictionaries, and when I display the class in a property grid and expand the dictionary I have the key string appearing on the left and the value appearing on the right -the value is editable. (I would like to be able to edit the key from this display as well but I believe that is not part of the property grid control).

The problem comes when attempting to add new entries to the dictionary. The collection editor opens, but the add/remove buttons are disabled and it seems the type it is expecting me to add is either a string or a DictionaryEntry, when I need to be able to add or edit both the key and the value.

This is my first forray into reflection-based programming so the solution is beyond me. Specifying a custom property editor, maybe?

Any help in the matter would be very much appreciated! Thanks in advance,

Robert
