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?

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.
}

Remember to add the method, e.g. in the form ctor:

public MyForm()
{
    InitializeComponent();

    this.FormClosing += MyForm_FormClosing;
}
