Is there a WinForms control to show and hide another WinForms control?

Question

是否有一个WinForms控件可以显示和隐藏另一个类似于TreeNode折叠按钮概念的WinForms控件？

Answer 1

The easy way to do it is add a button and a checkbox to a form, add an event handler for the checkbox CheckedChanged event and in the event handler code simply add:

button1.Visible = !checkBox1.Checked;

The better way to do it would be with data binding and INotifyProperyChanged

Answer 2

Do you mean something similar to an Accordian?

You could write wrappers for all the controls you want to use and make all their visibilities depend on the state of another control.

    private delegate void ToggleVoid();
    private static event ToggleVoid VisibilityToggle;

    private void Form1_Load(object sender, EventArgs e)
    {
        DependantButton TestButton = new DependantButton();
        TestButton.SetBounds(100, 100, 100, 100);
        this.Controls.Add(TestButton);

        Button ToggleButton = new Button();
        ToggleButton.SetBounds(200, 200, 100, 100);
        ToggleButton.Click += OnToggleButtonClicked;
        this.Controls.Add(ToggleButton);
    }

    private void OnToggleButtonClicked(object sender, EventArgs e)
    {
        VisibilityToggle.Invoke();
    }

    private class DependantButton : Button
    {
        public DependantButton() : base()
        {
            VisibilityToggle += ToggleVisibility;
        }

        public void ToggleVisibility()
        {
            Visible = !Visible;
        }
    }
