Datagridview cellvalidating cancel
I would want to easier the Data Grid View Text Box Cell editing by allowing the user to validate their entry by pressing Enter or cancel it by pressing Esc. Width = 195; -- -- rows local row = dotnetobject "Data Grid View Row"; local cell = dotnetobject "Data Grid View Text Box Cell"; row. but when Data Grid View control is in Max Rollout it doesn't work. I will try to restore this editing behavior inside max rollouts by extending the current Data Grid View like you did...I already used a hook from Denis for the Tree View label editing ( unless it involves Windows Messages scary hooks that I do not still fully understand :) At least, I don't know where and how you find the messages to be sent. but i don't think that this way is appropriate for you.

It could work but I wouldn't get the Escape key, anyways... by writing custom Data Grid View control derived from the Data Grid View class, and overriding Process Dialog Key and Process Data Grid View Key methods... Should I set the Multi Line property of the control, then check the keys and cancel the Enter to interpret it as a validation?The Cell End Edit event occurs only when the cell exits edit mode, which it cannot do if it fails validation.private void data Grid View1_Cell Validating(object sender, Data Grid View Cell Validating Event Args e) void data Grid View1_Cell End Edit(object sender, Data Grid View Cell Event Args e) And Voila!
