Quick Start Example

<Page
    xmlns:syncfusion="using:Syncfusion.UI.Xaml.Core">
    <Grid>
        <!-- Initials avatar -->
        <syncfusion:SfAvatarView
            x:Name="userAvatar"
            ContentType="Initials"
            AvatarName="John Doe"

            AvatarSize="Large"
            Background="CornflowerBlue"
            Foreground="White"
            AvatarShape="Circle"/>
    </Grid>
</Page>

using Syncfusion.UI.Xaml.Core;
using Microsoft.UI;

// Create avatar with initials
SfAvatarView avatarView = new SfAvatarView
{
    ContentType = AvatarContentType.Initials,
    AvatarName = "John Doe",
    InitialsType = AvatarInitialsType.DoubleCharacter,
    AvatarSize = AvatarSize.Large,
    Background = new SolidColorBrush(Colors.CornflowerBlue),
    Foreground = new SolidColorBrush(Colors.White),
    AvatarShape = AvatarShape.Circle
};

// Add to UI
this.Content = avatarView;

Common Patterns

1. User Profile Avatar with Initials

<syncfusion:SfAvatarView
    ContentType="Initials"
    AvatarName="Sarah Johnson"
    InitialsType="DoubleCharacter"
    AvatarSize="ExtraLarge"
    AvatarShape="Circle"
    Background="#FF6A5ACD"
    Foreground="White"/>

When to use: User profiles, account pages, settings screens.

2. Contact List with Custom Images

<ListView ItemsSource="{x:Bind Contacts}">
    <ListView.ItemTemplate>
        <DataTemplate x:DataType="local:Contact">
            <StackPanel Orientation="Horizontal" Spacing="10">
                <syncfusion:SfAvatarView
                    ContentType="CustomImage"
                    ImageSource="{x:Bind ProfileImagePath}"
                    AvatarSize="Medium"
                    AvatarShape="Circle"/>
                <TextBlock Text="{x:Bind Name}" VerticalAlignment="Center"/>
            </StackPanel>
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

When to use: Contact lists, chat contacts, team directories.

3. Chat Message with Avatar Character

<StackPanel Orientation="Horizontal" Spacing="10">
    <syncfusion:SfAvatarView
        ContentType="AvatarCharacter"
        AvatarCharacter="Avatar15"
        AvatarSize="Small"
        AvatarShape="Circle"/>
    <Border Background="LightGray"
            CornerRadius="8"
            Padding="10">
        <TextBlock Text="Hello! How are you?"/>
    </Border>
</StackPanel>

When to use: Chat interfaces, comment sections, messaging apps.

4. Group Avatar (Multiple Users)

<syncfusion:SfAvatarView
    ContentType="Group"
    GroupSource="{x:Bind TeamMembers}"
    ImageSourceMemberPath="ProfileImage"
    InitialsMemberPath="Name"
    BackgroundColorMemberPath="BackgroundColor"
    InitialsColorMemberPath="InitialsColor"
    AvatarSize="Large"/>

public class TeamMember
{
    public string Name { get; set; }
    public string ProfileImage { get; set; }
    public Color BackgroundColor { get; set; }
    public Color InitialsColor { get; set; }
}

public ObservableCollection<TeamMember> TeamMembers { get; set; } = new()
{
    new TeamMember { ProfileImage = "user1.png" },
    new TeamMember { Name = "Alex", BackgroundColor = Colors.LightBlue, InitialsColor = Colors.Navy },
    new TeamMember { ProfileImage = "user3.png" }
};

When to use: Team displays, group chats, collaborative features showing multiple participants.

5. Dynamic Avatar Based on Data Availability

private void ConfigureAvatar(User user)
{
    if (!string.IsNullOrEmpty(user.ProfileImageUrl))
    {
        // Use custom image if available
        avatarView.ContentType = AvatarContentType.CustomImage;
        avatarView.ImageSource = new BitmapImage(new Uri(user.ProfileImageUrl));
    }
    else if (!string.IsNullOrEmpty(user.FullName))
    {
        // Use initials if no image
        avatarView.ContentType = AvatarContentType.Initials;
        avatarView.AvatarName = user.FullName;
        avatarView.InitialsType = AvatarInitialsType.DoubleCharacter;
        avatarView.Background = GetColorFromName(user.FullName);
    }
    else
    {
        // Use default avatar character
        avatarView.ContentType = AvatarContentType.AvatarCharacter;
        avatarView.AvatarCharacter = AvatarCharacter.Avatar1;
    }
}

When to use: Fallback strategy when user data varies in completeness.

6. Square Avatar with Border for App Icons

<syncfusion:SfAvatarView
    ContentType="CustomImage"
    ImageSource="AppIcon.png"
    AvatarShape="Square"
    AvatarSize="Large"
    BorderBrush="Gray"
    BorderThickness="1"
    CornerRadius="8"/>

When to use: App icons, service logos, organization badges, square profile images.

7. Gradient Background Avatar with Initials

<syncfusion:SfAvatarView
    ContentType="Initials"
    AvatarName="Emma Wilson"
    InitialsType="DoubleCharacter"
    AvatarSize="Large"
    Foreground="White">
    <syncfusion:SfAvatarView.Background>
        <LinearGradientBrush StartPoint="0,0" EndPoint="1,1">
            <GradientStop Color="#FF6B5ACD" Offset="0"/>
            <GradientStop Color="#FF4169E1" Offset="1"/>
        </LinearGradientBrush>
    </syncfusion:SfAvatarView.Background>
</syncfusion:SfAvatarView>

When to use: Modern, visually appealing avatars with branded gradients.

Implementation Tips

1. Initials Generation:

- SingleCharacter: First letter of AvatarName ("Alex" → "A") - DoubleCharacter single word: First and last letter ("Alex" → "AX") - DoubleCharacter multiple words: First letter of first two words ("John Doe" → "JD")

1. Avatar Character Selection: 25 pre-defined avatars (Avatar1-Avatar25) provide diverse representation without custom images.
2. Group View Limitations: Supports up to 3 items. If more items in GroupSource, only first 3 are displayed.
3. Image Loading: Use BitmapImage with ms-appx:/// or https:// URIs. Handle loading errors gracefully.
4. Background Colors: Generate consistent colors from user names using hash functions for visual consistency.
5. Size Guidelines:

- ExtraSmall (32x32): Navigation bars, compact lists - Small (48x48): Chat messages, dense lists - Medium (64x64): Standard lists, cards - Large (96x96): Profile pages, prominent displays - ExtraLarge (128x128): Large profile headers, focus areas

1. Performance: Initials render faster than images. Use initials for long lists, custom images for detail views.
2. Accessibility: Avatar images should have AutomationProperties.Name set to user's name for screen readers.
3. Theme Integration: Use ThemeResource for Background to auto-adapt to light/dark themes: Background="{ThemeResource SystemAccentColor}"
4. Caching: Cache avatar images to avoid repeated downloads. Use local storage for frequently accessed avatars.
