Visual Elements
A feature that allows developers to incorporate imagery into the chip control by displaying an optional avatar, enhancing the chip’s visual appeal and contextual representation.
Overview
The Visual Elements feature provides an optional mechanism to display an image (avatar) within the chip control. By setting the Avatar
property, developers can include a representative image—such as a user picture or an icon—that aligns with the chip’s content. This feature improves the aesthetic and functional context of the chip by visually associating it with a person, brand, or concept.
Key Points
Property
Avatar: An optional image property that, when set, displays an avatar inside the chip.
Integration
The avatar is rendered within a circular clipping region, ensuring it appears as a neatly contained element.
Visual Enhancement
Incorporating an avatar can add personality and clarity to chips, making them ideal for user lists, contact selections, or category representations.
Layout Impact
The avatar occupies space within the chip, and its size is controlled by related properties (such as avatarSize and avatarPadding), which adjust the layout of the chip’s text.
Best Practices
Use high-quality images
Select images that are clear and appropriately sized to prevent pixelation or distortion when displayed in the chip control.
Maintain consistent styling
Ensure that the avatar’s styling (e.g., circular clipping) is consistent with the overall design language of your application for a unified user experience.
Optimize image size
Use images with dimensions that match or are close to the intended avatar size (default is 24x24 pixels) to reduce scaling overhead and improve rendering performance.
Provide fallback handling
In scenarios where no avatar is provided, ensure the chip still displays correctly without any placeholder artifacts.

Common Pitfalls
Using low-resolution images
Low-resolution or poorly scaled images may appear blurry or pixelated when rendered in the chip, negatively impacting the overall visual quality.
Overcrowding the chip layout
Adding an avatar without adjusting the chip’s padding may cause the image to overlap with text or other elements. Always verify that the layout accommodates the avatar appropriately.
Neglecting proper disposal of images
If images are loaded dynamically, failing to dispose of them correctly can lead to memory leaks. Dispose of images when no longer needed, or ensure they are managed by the control.

Usage Scenarios
Contact Lists
Display user avatars in a list of contacts where each chip represents an individual, making identification quick and intuitive.
Social Media Tags
Use avatars to visually associate chips with user-generated content, such as profile pictures in social media applications.
Branding and User Profiles
Incorporate brand logos or profile pictures in chips used for selecting user profiles, accounts, or team members in enterprise applications.
Code Example: Contact List Chip
Real Life Usage Scenarios
Messaging Applications
In messaging or chat applications, use avatars in chips to represent different conversation threads or contacts, making the interface more personable.
Employee Directory
For an internal company directory, display employee photos within chips to quickly identify individuals by their visual representation.
Customer Management Systems
Utilize customer avatars in a CRM tool where each chip corresponds to a customer record, enhancing recognition and navigation in customer lists.
Code Example: Employee Directory Chip
Troubleshooting Tips
Verify image dimensions
Ensure that the avatar image dimensions are appropriate for the chip's layout; resizing images before assignment can prevent distortion.
Test layout adjustments
Adjust the chip’s padding properties if the avatar overlaps with text or other elements; use debugging tools to inspect the rendered layout and adjust accordingly.
Monitor image disposal
Check that images assigned to the avatar property are properly disposed of when no longer needed, especially in dynamic applications, to prevent memory leaks.
Ensure correct image format
Use image formats that are supported by .NET (e.g., PNG, JPEG) and verify that images are not corrupted to avoid runtime errors during rendering.
Review
Functionality
The Visual Elements feature effectively integrates images into the chip control, enhancing both the aesthetic appeal and contextual clarity of the control.
Customization
By simply setting the Avatar property, developers can add an image to the chip, while the control handles circular clipping and layout adjustments to maintain a clean appearance.
Integration
The feature is easy to integrate and requires minimal code changes, making it a flexible option for a variety of applications, from social apps to enterprise tools.
Summary
The Visual Elements feature allows developers to seamlessly integrate an optional avatar into the chip control, providing a visual representation that enhances user identification and branding. By setting the Avatar property and adjusting related layout properties, the chip control can display high-quality images in a circular clipped format. This feature is particularly valuable in contact lists, social media interfaces, and any application where visual representation plays a key role.

Integration Checklist
Load high-quality images
Ensure that images used for avatars are of sufficient resolution and properly sized for the chip layout.
Set the Avatar property
Confirm that the Avatar property is assigned to the desired image.
Adjust layout as needed
Verify that the chip’s padding and layout accommodate the avatar without overlapping text or other elements.
Test across different themes
Ensure that the avatar displays consistently across various themes and background colors in your application.
FAQ
What happens if the Avatar property is not set?
If no image is assigned to the Avatar property, the chip will display without an avatar, using only its text and other visual properties.
Can I update the avatar image at runtime?
Yes, the Avatar property can be updated dynamically, and the chip will reflect the new image immediately.
How do I handle image disposal properly?
Dispose of images when they are no longer needed or clone images before assignment to ensure that disposal of the original image does not affect the control.
