WPF 回车转Tab实现跳转

WPF 回车转Tab实现跳转

1.重写窗体的KeyDown事件

Code Snippet

protected override void OnKeyDown(KeyEventArgs e)
{
if (e.Key == Key.Enter)
{
// MoveFocus takes a TraveralReqest as its argument.
TraversalRequest request = new TraversalRequest(FocusNavigationDirection.Next);

// Gets the element with keyboard focus.
UIElement elementWithFocus = Keyboard.FocusedElement as UIElement;

// Change keyboard focus.
if (elementWithFocus != null)
{
elementWithFocus.MoveFocus(request);
}
e.Handled = true;
}
base.OnKeyDown(e);
}

2.在基容器如Grid的KeyDown事件中

Code Snippet

<Grid KeyDown="Grid_KeyDown">

实现代码

Code Snippet

private void Grid_KeyDown(object sender, KeyEventArgs e)
{
var uie = e.OriginalSource as UIElement;
if (e.Key == Key.Enter)
{
uie.MoveFocus(new TraversalRequest(FocusNavigationDirection.Next));
e.Handled = true;
}
}
