推荐答案

创建一对具有所有适当控件的子控件，而不是使用单独的表单，并根据要求显示/隐藏每个子控件必要时进行控制.

编辑=============

只需将适当的数据库更新代码添加到Show或Hide事件处理程序即可.隐藏该窗体后，请它更新数据库.当它显示时，让它从数据库中检索信息(或进行适当初始化控件所需的任何处理.

万一您不知道，表单只不过是控件本身. UserControl就像无边界表单一样(它可以包含其他表单控件，例如文本框，按钮等，甚至其他UserControls.因此，很容易推断出可以将UserControl放置在表单上.

Instead of using separate forms, create a pair of child controls that have all of the appropriate controls on it, and depending on requirements, show/hide each child control when necessary.

EDIT =============

Simply add the appropriate database updating code to the Show or Hide event handlers. When the form is hidden, have it update the database. When it''s show, have it retrieve info from the database (or whatever processing needs to happen to properly initialize the control.

Just in case you didn''t know, a form is nothing more than a control itself. A UserControl is like a borderless form (it can contain other form controls, like text boxes, buttons, etc, or even additional UserControls. It is therefore easy to deduce that you can place the UserControl onto a form.
