如何防止表单对象关闭放置? [英] How do I prevent a form object from disposing on close?

问题描述

我正在使用MDIParent表格.当我关闭其子项时，该子项的对象将处置.有没有一种方法可以将儿童可见性设置为false而不是进行处理?

I am using an MDIParent Form. When I close its child, the object of the child disposes. Is there a way to set child visibility to false instead of disposing?

推荐答案

默认情况下，关闭表单时，该表单将被处理.您必须重写Closing事件以防止它发生，例如:

By default, when you close a form, it will be disposed. You have to override the Closing event to prevent it, for example:

// Use this event handler for the FormClosing event.
private void MyForm_FormClosing(object sender, FormClosingEventArgs e)
{
  this.Hide();
  e.Cancel = true; // this cancels the close event.
}
