# Interactive Features

A feature that governs how the chip control responds to user input by enabling selection, handling click events, and optionally displaying a close button for removal.

## Overview

The Interactive Features of the chip control determine how users interact with it. With properties like EnableSelection, IsSelected, and ShowCloseButton, along with corresponding events such as ChipClicked, CloseClicked, and SelectionChanged, developers can customize both the behavior and visual feedback of the chip. This functionality is essential for creating responsive and intuitive user interfaces where chips can be toggled, selected, or dismissed as needed.

### Key Points

<table><thead><tr><th width="256">Aspect</th><th>Details</th></tr></thead><tbody><tr><td>Selection Control</td><td><strong>EnableSelection</strong>: Allows the chip to be selected or deselected by the user. <strong>IsSelected</strong>: Indicates the current selection state of the chip, toggling its appearance accordingly.</td></tr><tr><td>Close Functionality</td><td><strong>ShowCloseButton</strong>: Determines whether a close (X) button is displayed on the chip, enabling users to remove or dismiss the chip from the interface.</td></tr><tr><td>Event Handling</td><td><strong>ChipClicked Event</strong>: Triggered when the main body of the chip is clicked. <strong>CloseClicked Event</strong>: Fired when the close button is clicked, optionally triggering auto-disposal if enabled. <strong>SelectionChanged Event</strong>: Notifies when the selection state changes.</td></tr><tr><td>Behavior Customization</td><td><strong>AutoDisposeOnClose</strong> (Behavior): If set to true, the chip will automatically remove itself from its parent container when the close button is clicked, streamlining resource management.</td></tr></tbody></table>

### Best Practices

| Practice                                    | Explanation                                                                                                                                                                                                    |
| ------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Ensure clear interactive cues               | Use visual feedback (such as changes in color or checkmarks) to clearly indicate when a chip is selected or hovered, enhancing usability.                                                                      |
| Separate click actions appropriately        | Distinguish between clicking on the main chip area (to select) and clicking the close button (to dismiss), to avoid confusion in user interactions.                                                            |
| Manage selection logic consistently         | When multiple chips are grouped together, ensure that enabling selection (via EnableSelection and IsSelected) adheres to expected radio-button-like behavior, possibly with additional group management logic. |
| Leverage event subscriptions for UI updates | Attach handlers to events like ChipClicked, CloseClicked, and SelectionChanged to trigger further application logic or update related UI elements when interactions occur.                                     |
| Consider auto-disposal where appropriate    | Use AutoDisposeOnClose to automatically clean up removed chips, reducing the need for manual disposal and minimizing memory leaks in dynamic interfaces.                                                       |

#### Code Example: Basic Interactive Chip

```csharp
// Create a chip with interactive selection enabled.
var interactiveChip = new SiticoneGroupChip
{
    Text = "Interactive Chip",
    
    // Allow selection behavior
    EnableSelection = true,
    
    // Initially not selected
    IsSelected = false,
    
    // Display a close button for removal
    ShowCloseButton = true,
    
    // Automatically dispose the chip upon close if desired
    AutoDisposeOnClose = true
};

// Subscribe to click events to handle interactions
interactiveChip.ChipClicked += (sender, e) =>
{
    // Toggle selection if enabled
    interactiveChip.IsSelected = !interactiveChip.IsSelected;
    Console.WriteLine($"Chip clicked. New selection state: {interactiveChip.IsSelected}");
};

interactiveChip.CloseClicked += (sender, e) =>
{
    // Optionally, perform additional logic on chip close
    Console.WriteLine("Chip close button clicked.");
};

interactiveChip.SelectionChanged += (sender, e) =>
{
    // Log or update UI when selection state changes
    Console.WriteLine("Chip selection state changed.");
};

// Add the chip to a container (e.g., a Form or Panel)
this.Controls.Add(interactiveChip);
```

### Common Pitfalls

<table><thead><tr><th width="334">Pitfall</th><th>Explanation</th></tr></thead><tbody><tr><td>Overloading the chip with interactions</td><td>Combining too many interactive behaviors (selection, close, hover animations) without clear visual separation may confuse users about the chip’s function.</td></tr><tr><td>Inconsistent state management</td><td>Not updating IsSelected in sync with the chip’s visual appearance (or vice versa) can lead to mismatches where the UI does not accurately reflect the chip’s state.</td></tr><tr><td>Event mismanagement</td><td>Failing to subscribe or inadvertently subscribing to multiple conflicting events may lead to unexpected behaviors, such as multiple event handlers firing simultaneously.</td></tr><tr><td>Ignoring group dynamics</td><td>When chips are grouped, not enforcing mutual exclusivity (i.e., radio button behavior) can lead to multiple chips being selected at once, causing confusion in the interface.</td></tr></tbody></table>

#### Code Example: Avoiding Interactive Pitfalls

```csharp
// Create two chips that should behave like radio buttons.
var chipA = new SiticoneGroupChip
{
    Text = "Option A",
    EnableSelection = true,
    IsSelected = false,
    Group = "Options" // Grouping enables radio-button behavior.
};

var chipB = new SiticoneGroupChip
{
    Text = "Option B",
    EnableSelection = true,
    IsSelected = false,
    Group = "Options"
};

// Subscribe to selection changed events to update the UI.
chipA.SelectionChanged += (sender, e) =>
{
    Console.WriteLine("Option A selection changed.");
};

chipB.SelectionChanged += (sender, e) =>
{
    Console.WriteLine("Option B selection changed.");
};

// Add the chips to a panel.
optionsPanel.Controls.Add(chipA);
optionsPanel.Controls.Add(chipB);
```

### Usage Scenarios

<table><thead><tr><th width="252">Scenario</th><th>Description</th></tr></thead><tbody><tr><td>Tag or Filter Selection</td><td>Use interactive chips to allow users to select tags or filters. Chips can toggle selection and provide immediate visual feedback through state changes, such as checkmarks or color shifts.</td></tr><tr><td>Removable Items</td><td>Incorporate a close button to let users dismiss items (such as notifications, tags, or list elements) directly from the UI, streamlining content management.</td></tr><tr><td>Dynamic Options in Forms</td><td>Integrate chips as interactive options in forms, where clicking a chip toggles its selected state, and group behavior ensures that only one option is active at a time.</td></tr></tbody></table>

#### Code Example: Removable Filter Chip

```csharp
// Create a chip used as a filter with interactive selection and a close button.
var filterChip = new SiticoneGroupChip
{
    Text = "Active Filter",
    EnableSelection = true,
    IsSelected = true,
    ShowCloseButton = true,
    AutoDisposeOnClose = true
};

// When the chip is clicked, toggle its selection state.
filterChip.ChipClicked += (sender, e) =>
{
    filterChip.IsSelected = !filterChip.IsSelected;
};

// When the close button is clicked, remove the chip.
filterChip.CloseClicked += (sender, e) =>
{
    Console.WriteLine("Filter chip removed.");
};

// Add the chip to a filter panel.
filterPanel.Controls.Add(filterChip);
```
