Hello friends,

I have lot of editable controls(textboxes, datagrid views, comboboxes etc) on my winform. Currently if i select a particular control and press Ctrl+Z or +Y, it works only for that particular selected control. But our requirement is to use the Undo/redo functionality for all the controls.

For eg.: If user has modified 30 controls then when he does Undo/redo, the changes should get reflected for all controls one after another. Its like till u finished undo-ing/redo-ing the last modified control.

How to achieve this? Please suggest.
Thanks

You have to implement your own system.

You would have to remember the order in which controls have accepted user input. Be sure to have the form's KeyPreview property set so you can change focus whenever appropriate during a sequence of several Undos.

Or do it right, data-bind all the controls and work on the underlying data. There's an article on an Undo/Redo Buffer Framework here at CP. Don't be afraid of the broken link to the other article on Mementos. The search works quite well.

Good luck.
