My main objective is to make the Enter key not move to the next row in the grid. If that doesn't work, you can create a Key Press event on the cell and emulate pressing Enter on the cell, but that may mess with the users UI, just put the carat back where it was.

I still want the enter key to validate and end edit mode.

It turns out that this is trickier than it might seem and doesn’t work great out of the box from .

It’s important to note that this event will get called twice, once on changing the state of the cell to dirty (before committing changes) and once when changing the cell state back to ‘clean’ (after the changes have been committed).

For this reason, before preforming any action, it checks to see when the current cell is dirty or not. The form loads by default to only handle the Cell Value Changed event itself, which means we will immediately notice the problem at hand.

This helps identify when, and in what order, events are being handled without explicitly having to set breakpoints and wait for the code to catch each event.

In the options group box, you can choose to include event handlers notifications or not.

Further, let’s say that you’d like to know as soon as the user has made a change to their selection.

You might want to handle this for a number of reasons: to enable a save button, to change the appearance of selected items, to display a pop-up window, or to check for consistency against other choices.

What I really want is some flavour of End Edit() that behaves just like pressing enter on the last row of a grid with adding disabled. my version is a slight different from yours, because when i move to the other cell, and my code returns e.cancel=false in the cell validating event, an error will be generated, says that: "operation did not succeed, because the program cannot commit or quit a cell value change". this is my code: Protected Overrides Function Process Dialog Key(By Val key Data As System.

Cells(1) frm Ok_Click(Me, New Event Args) Catch ex As Exception End Try Return True End If End If Return My Base.

Also, the drop down list will add / remove handlers so you can easily test out which handlers do what without having to specifically comment out lines of code.

I'm using a Data Grid View in my Win Forms application. Process Dialog Key(key Data) End Function No, but you can manually fire the Cell Validating event. All events are is a class using the Observer Pattern, they're no different than any other method.

What if someone is able to make a selection without a click event?
