# Built-In Context Menu Operations

## Overview

The Built-In Context Menu Operations feature streamlines user interaction by presenting a context menu when the control is right-clicked. This menu includes options to increment or decrement the slider's value by the defined step, as well as an option to open a dialog for manual value entry. These operations enhance usability by offering an alternative to direct manipulation via dragging or keyboard input.

### Best Practices

The table below provides recommendations for effectively utilizing the built-in context menu operations:

| Practice                                 | Recommendation                                                                                                                                 |
| ---------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------- |
| Maintain Consistent Step Increments      | Ensure the Step property is set appropriately so that increments and decrements align with user expectations.                                  |
| Customize Menu Appearance                | Use the ContextMenuFont property to harmonize the context menu's typography with your application's design.                                    |
| Disable in Read-Only Mode                | When the control is set to read-only (IsReadOnly = true), consider disabling or customizing context menu operations to prevent user confusion. |
| Integrate with Other Feedback Mechanisms | Combine context menu operations with visual feedback (e.g., tooltips) to reinforce the effect of value changes.                                |

### Common Pitfalls

The table below outlines frequent issues and their suggested solutions when working with built-in context menu operations:

<table><thead><tr><th width="368">Pitfall</th><th>Solution</th></tr></thead><tbody><tr><td>Context menu not appearing on right-click</td><td>Ensure that the control’s OnMouseDown event is checking for a right-click (MouseButtons.Right) and that the context menu is properly initialized.</td></tr><tr><td>Inconsistent value changes</td><td>Verify that the IncrementValue and DecrementValue methods correctly adjust the slider's value and respect the defined Minimum and Maximum limits.</td></tr><tr><td>Manual value dialog not validating input</td><td>When implementing SetValueManually, include robust input validation to ensure that only valid integer values within the slider’s range are accepted.</td></tr><tr><td>Customizations conflicting with defaults</td><td>When overriding context menu properties, ensure that modifications do not interfere with the base functionality of the control.</td></tr></tbody></table>

### Troubleshooting Tips

When issues arise with the built-in context menu, consider the following troubleshooting steps:

| Issue                                          | Troubleshooting Tip                                                                                                                       |
| ---------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------- |
| Context menu does not open on right-click      | Check that the right-click event in OnMouseDown triggers the context menu display and that no other mouse event handlers conflict.        |
| Menu items do not trigger the expected actions | Verify that the event handlers (IncrementValue, DecrementValue, SetValueManually) are correctly attached to the corresponding menu items. |
| Customizations are not reflecting in the menu  | Confirm that changes to ContextMenuFont or other styling properties are applied by calling UpdateContextMenuFont() after modification.    |

### Integration Examples

#### Basic Context Menu Operations

This example demonstrates how to integrate and use the built-in context menu operations in a WinForms application.

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

namespace ContextMenuDemo
{
    public class MainForm : Form
    {
         public MainForm()
         {
             this.Text = "Built-In Context Menu Demo";
             this.Size = new Size(500, 250);

             // Initialize and configure the slider
             SiticoneHSlider slider = new SiticoneHSlider
             {
                 Location = new Point(20, 50),
                 Size = new Size(400, 40),
                 Minimum = 0,
                 Maximum = 100,
                 Step = 5,
                 Value = 50
             };

             // Right-clicking the slider will show the built-in context menu
             this.Controls.Add(slider);
         }

         [STAThread]
         public static void Main()
         {
             Application.EnableVisualStyles();
             Application.Run(new MainForm());
         }
    }
}
```

#### Advanced Customization of Context Menu

         {
             this.Text = "Advanced Context Menu Operations Demo";
             this.Size = new Size(500, 250);

             // Initialize and configure the slider with a custom context menu font
             SiticoneHSlider slider = new SiticoneHSlider
             {
                 Location = new Point(20, 50),
                 Size = new Size(400, 40),
                 Minimum = 0,
                 Maximum = 100,
                 Step = 5,
                 Value = 50,
                 ContextMenuFont = new Font("Arial", 10f)
             };

             // Add the slider to the form
             this.Controls.Add(slider);
         }

         [STAThread]
         public static void Main()
         {
             Application.EnableVisualStyles();
             Application.Run(new MainForm());
