How do I prevent a form object from disposing on close?

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.
}

Answer 2

You can cancel the close event and hide instead.

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
    {
        e.Cancel = true;
        this.Hide();
    }
