# Built-In Context Menu Functionality

## Overview

The Built-In Context Menu Functionality allows users to interact with the SiticoneHRangeTrackBar control using right-click actions on the slider thumbs. When a thumb is right-clicked, a context menu appears with options to increment, decrement, or set the value directly via an input dialog. This built-in functionality simplifies value adjustments without needing external controls or additional coding, and it integrates seamlessly with the control’s existing behavior.

## Common Pitfalls

Avoid these common pitfalls when working with the built-in context menus:

| Pitfall                                     | Explanation                                                                                                 | How to Avoid                                                              |
| ------------------------------------------- | ----------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------- |
| Overriding Without Preserving Functionality | Customizing context menu items without retaining the default behavior can break the built-in functionality. | Ensure that any customizations still invoke the underlying command logic. |
| Ignoring Validation Requirements            | Allowing custom values that fall outside the defined range can lead to unexpected behavior.                 | Always validate new values against Minimum and Maximum properties.        |
| Failing to Unsubscribe (if extended)        | Extending context menu functionality without proper event unsubscription may lead to memory leaks.          | Manage event subscriptions carefully, especially in dynamic UIs.          |

## Usage Scenarios

The following table illustrates common scenarios where the built-in context menus are particularly useful:

| Scenario                                | Description                                                                                                          | Example Configuration                                                                        |
| --------------------------------------- | -------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------- |
| Quick Adjustments in Data Entry         | Users can easily increase or decrease values on the fly during data entry without switching controls.                | Default settings with right-click enabled on both thumbs.                                    |
| Custom Value Entry in Specialized Forms | Allows users to directly input a specific value when the slider’s granularity does not match the required precision. | Use the "Set Value..." option to invoke a validated input dialog.                            |
| Real-Time Parameter Tuning              | Useful in applications like audio or video editing, where precise control adjustments are needed quickly.            | Right-click on the thumb to make fine adjustments without navigating away from the timeline. |
