C# 增加按tab键就下一个文本框 private MaintenanceMetrics Closing += MaintenanceMetrics_Closing; gridRowDefinitionsAddnew RowDefinition Height = new GridLength70 ; grid

To add the functionality of moving to the next TextBox when the Tab key is pressed, you can add the following code to the Text_KeyDown event handler:

private void Text_KeyDown(object sender, KeyEventArgs e) { if (e.Key == Key.Tab) { e.Handled = true; var uiElement = e.OriginalSource as UIElement; if (uiElement != null) { uiElement.MoveFocus(new TraversalRequest(FocusNavigationDirection.Next)); } } }

This code checks if the Tab key was pressed, and if so, sets the Handled property of the event to true to prevent the default behavior of moving the focus to the next control in the tab order. Then it gets the original source of the event (which should be the TextBox that received the event), and calls the MoveFocus method to move the focus to the next control in the tab order
