Question

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?

Answer 1

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.
}
