# Trigger Feedback

## **Overview**

The **`TriggerReadOnlyFeedback()`** method of the `SiticoneCheckBox` control provides developers with the ability to programmatically activate feedback mechanisms when the checkbox is set to read-only. This method is particularly useful in scenarios where user interactions need to be restricted, and immediate feedback is required to inform the user about the read-only state. By invoking this method, the control can visually indicate its non-interactive status through animations (e.g., shake effect) and auditory cues (e.g., beep sound), thereby enhancing the user experience and accessibility.

#### **Method Signature**

```csharp
public void TriggerReadOnlyFeedback()
```

#### **Detailed Description**

The **`TriggerReadOnlyFeedback()`** method serves as an explicit mechanism to provide feedback when the `SiticoneCheckBox` is in a read-only state. When called, the method checks if the checkbox is indeed read-only (`IsReadOnly` property is `true`). If so, it proceeds to execute feedback actions based on the control's configuration:

1. **Auditory Feedback (`CanBeep`):**\
   If the `CanBeep` property is set to `true`, the method plays a beep sound using the system's default beep sound. This auditory cue alerts users that their interaction is not permitted.
2. **Visual Feedback (`CanShake`):**\
   If the `CanShake` property is `true` and the control is not already in the process of shaking (`_isShaking` is `false`), the method initiates a shake animation. This visual effect serves as a clear indication that the checkbox is currently non-interactive.

By providing both auditory and visual feedback, the method ensures that users receive immediate and noticeable cues about the read-only status of the checkbox, thereby preventing confusion and enhancing usability.

#### **Usage**

Developers can call the **`TriggerReadOnlyFeedback()`** method in response to specific events or conditions where the checkbox needs to inform the user about its read-only state. This can be particularly useful in form validations, conditional UI states, or when certain functionalities are temporarily disabled.

#### **Example**

**Example 1: Triggering Read-Only Feedback Upon Invalid Input**

```csharp
using System;
using System.Drawing;
using System.Windows.Forms;
using SiticoneNetFrameworkUI;

public class ReadOnlyFeedbackForm : Form
{
    private SiticoneCheckBox readOnlyCheckBox;
    private Button validateButton;

    public ReadOnlyFeedbackForm()
    {
        InitializeComponent();
    }

    private void InitializeComponent()
    {
        this.readOnlyCheckBox = new SiticoneCheckBox();
        this.validateButton = new Button();
        this.SuspendLayout();

        // 
        // readOnlyCheckBox
        // 
        this.readOnlyCheckBox.Text = "Accept Terms and Conditions";
        this.readOnlyCheckBox.Location = new Point(50, 50);
        this.readOnlyCheckBox.Size = new Size(250, 35);
        this.readOnlyCheckBox.IsReadOnly = true;       // Set checkbox to read-only
        this.readOnlyCheckBox.CanBeep = true;          // Enable beep sound
        this.readOnlyCheckBox.CanShake = true;         // Enable shake animation

        // 
        // validateButton
        // 
        this.validateButton.Text = "Validate";
        this.validateButton.Location = new Point(50, 100);
        this.validateButton.Click += new EventHandler(this.ValidateButton_Click);

        // 
        // ReadOnlyFeedbackForm
        // 
        this.ClientSize = new Size(350, 200);
        this.Controls.Add(this.readOnlyCheckBox);
        this.Controls.Add(this.validateButton);
        this.Text = "SiticoneCheckBox - TriggerReadOnlyFeedback Example";
        this.ResumeLayout(false);
    }

    private void ValidateButton_Click(object sender, EventArgs e)
    {
        // Attempt to toggle the checkbox state
        if (readOnlyCheckBox.IsReadOnly)
        {
            // Trigger read-only feedback to inform the user
            readOnlyCheckBox.TriggerReadOnlyFeedback();
        }
        else
        {
            // Toggle the checkbox state if not read-only
            readOnlyCheckBox.Checked = !readOnlyCheckBox.Checked;
        }
    }
}
```

**Explanation:**

* The form contains a `SiticoneCheckBox` labeled `"Accept Terms and Conditions"`, which is set to read-only (`IsReadOnly = true`).
* The `CanBeep` and `CanShake` properties are enabled to allow auditory and visual feedback when the checkbox is interacted with while in a read-only state.
* A `Validate` button is provided. When clicked, it attempts to toggle the checkbox's state.
  * If the checkbox is read-only, it invokes the `TriggerReadOnlyFeedback()` method to inform the user that the checkbox cannot be interacted with.
  * If the checkbox is not read-only, it toggles the `Checked` state as usual.

This example demonstrates how to use the `TriggerReadOnlyFeedback()` method to provide immediate feedback to users attempting to interact with a read-only checkbox.
