Implementing Syncfusion Windows Forms Toggle Button

Welcome to the Toggle Button implementation guide. The Toggle Button control allows you to toggle between two contrasting states (Active and Inactive) with full customization options.

When to Use This Skill

Use this skill when you need to:

• Create toggle buttons with two contrasting states (ON/OFF, YES/NO, etc.)
• Customize the appearance of active and inactive states
• Switch between text and image display modes
• Implement custom styling with renderers
• Handle toggle events and state changes
• Build interactive Windows Forms applications with toggle controls

Component Overview

The Toggle Button is a Windows Forms control that presents two distinct states:

• Active State: Typically used for "ON", "YES", or enabled conditions
• Inactive State: Typically used for "OFF", "NO", or disabled conditions

Users can toggle between states by clicking the button or pressing the Space key.

Key Capabilities

• Configurable Active and Inactive states with independent styling
• Display modes: Text or Image
• Event handling for state changes
• Custom rendering support
• Full color and border customization per state

Quick Start Example

Here's a minimal example to create and configure a Toggle Button:

using Syncfusion.Windows.Forms.Tools;
using System.Drawing;

// Create and add Toggle Button to form
ToggleButton toggleButton = new ToggleButton();
toggleButton.Location = new System.Drawing.Point(50, 50);
toggleButton.Size = new System.Drawing.Size(100, 40);
toggleButton.Name = "toggleButton1";

// Configure Active state
toggleButton.ActiveState.Text = "ON";
toggleButton.ActiveState.BackColor = Color.FromArgb(1, 115, 199);
toggleButton.ActiveState.ForeColor = Color.White;

// Configure Inactive state
toggleButton.InactiveState.Text = "OFF";
toggleButton.InactiveState.BackColor = Color.White;
toggleButton.InactiveState.ForeColor = Color.FromArgb(80, 80, 80);

// Set initial state
toggleButton.ToggleState = ToggleButtonState.Inactive;

// Add to form
this.Controls.Add(toggleButton);

Common Patterns

Pattern 1: Binary State Toggle

Create a simple ON/OFF toggle button for boolean settings:

toggleButton.ActiveState.Text = "ON";
toggleButton.InactiveState.Text = "OFF";
toggleButton.ToggleState = ToggleButtonState.Inactive;

Pattern 2: Yes/No Toggle

Create a decision toggle:

toggleButton.ActiveState.Text = "YES";
toggleButton.InactiveState.Text = "NO";

Pattern 3: State-Based Colors

Apply different colors to visually indicate state:

// Active - Green
toggleButton.ActiveState.BackColor = Color.FromArgb(34, 177, 76);
toggleButton.ActiveState.ForeColor = Color.White;

// Inactive - Red
toggleButton.InactiveState.BackColor = Color.FromArgb(192, 0, 0);
toggleButton.InactiveState.ForeColor = Color.White;

Pattern 4: Custom Text Per State

Provide descriptive labels for each state:

toggleButton.ActiveState.Text = "Enabled";
toggleButton.InactiveState.Text = "Disabled";

Key Properties

Property	Purpose	Common Values
ToggleState	Current state of the button	ToggleButtonState.Active, ToggleButtonState.Inactive
ActiveState.Text	Text displayed when active	"ON", "YES", "Enabled"
InactiveState.Text	Text displayed when inactive	"OFF", "NO", "Disabled"
ActiveState.BackColor	Background color when active	Color values
InactiveState.BackColor	Background color when inactive	Color values
DisplayMode	What to display	DisplayType.Text, DisplayType.Image
Renderer	Custom appearance rendering	IToggleButtonRenderer implementation

Assembly Dependencies

To use Toggle Button, add these assemblies to your project:

• Syncfusion.Grid.Base
• Syncfusion.Grid.Windows
• Syncfusion.Shared.Base
• Syncfusion.Shared.Windows
• Syncfusion.Tools.Base
• Syncfusion.Tools.Windows

Next Steps

1. Start with Getting Started - Install dependencies and add the control
2. Configure States - Customize active and inactive appearance
3. Choose Display Mode - Text or image display
4. Add Styling - Apply custom renderers if needed
5. Handle Events - Respond to state changes in your application
