Hi,
I tried out your code, and it appears to work fine. WIth the exception that i had to add this:
void grid_CellExitedEditMode(object sender, CellExitedEditingEventArgs e)
{
isEditing = false;
}
Hitting enter exited edit mode for me no problem.
Now, i don't have any editing settings turned on, and i tried this on a TextColumn. If you have a custom editor or any editor that handles the enter key, then the xamGrid won't exit edit mode, as it defaults to the editor's key handling first.
