问题
I have a problem with datagrid control in wpf . when I press enter I want to load selected items in a set of controls, but it seems that datagrid.KeyDown is already handled and it goes to the next item.
I tried using keyup but this event fires when the datagrid keydown had been fired and datagrid goes to the next item.
any idea to handle keydown completely ?
回答1:
Use the PreviewKeyDown event instead of KeyDown
回答2:
Maybe KeyDown is handled by a ClassHandler.
Instance listeners come after class listeners.
A good explanation on MSDN.
