DataGridView Column Editor
The DataGridView Column Editor allows maintenance of columns within a datagridview. The editor consists
of two lists and eight buttons.
The editor supports nine (9) column types: button, checkbox, combobox, date/time picker, image, link,
masked text edit, numeric up/down, and text.
The edit window may be resized and a splitter is available to allow resizing the columns list.
