在vs2005中,关闭子窗体时如何使父窗体的控件(button)的enable属性为ture?

Question

父窗体:frmfather 里面还有button控件btnfrmchild,子窗体:frmchild,望高人赐教!!!

Answer 1

frmfather   里面button控件btnfrmchild所访问属性设为public,子窗体:frmchild构造函数中将frmfather   作为参数传入,子窗体的closing事件中加入frmfather. btnfrmchild.Enable=true;
OK!  

Answer 2

Form form4 = new Form();
            form4.Disposed += new EventHandler( form4_Disposed );
            form4.Show( this );        private void form4_Disposed( object sender, EventArgs e )
        {
            this.button1.Enabled = false;
        }

Answer 3

frmfather的load里
                        frmchild.Disposed   +=   new   EventHandler(   frmchild_Disposed   );
                        frmchild.Show(   this   );private   void   frmchild_Disposed(   object   sender,   EventArgs   e   )
                {
                        this.button1.Enabled   =   false;
                }
