下面的代码示例使用 Parent 属性和 FindForm 方法设置按钮及其窗体的父控件的属性。
// This example uses the Parent property and the Find method of Control to set
// properties on the parent control of a Button and its Form. The example assumes
// that a Button control named button1 is located within a GroupBox control. The
// example also assumes that the Click event of the Button control is connected to
// the event handler method defined in the example.
private:
void button1_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
// Get the control the Button control is located in. In this case a GroupBox.
Control^ control = button1->Parent;
// Set the text and backcolor of the parent control.
control->Text = "My Groupbox";
control->BackColor = Color::Blue;
// Get the form that the Button control is contained within.
Form^ myForm = button1->FindForm();
// Set the text and color of the form containing the Button.
myForm->Text = "The Form of My Control";
myForm->BackColor = Color::Red;
}
