This section explains how to bind StaticResource to ImageSource in Xamarin.Forms SfAvatarView.

Getting Started With Xamarin AvatarView (SfAvatarView)

Adding SfAvatarView reference

You can add SfAvatarView reference using one of the following methods:

Method 1: Adding SfAvatarView reference from nuget.org

Syncfusion Xamarin components are available in nuget.org. To add SfAvatarView to your project, open the NuGet package manager in Visual Studio, search for Syncfusion.Xamarin.Core, and then install it.

Method 2: Adding SfAvatarView reference from toolbox

Syncfusion also provides Xamarin Toolbox. Using this toolbox, you can drag the SfAvatarView control to the XAML page. It will automatically install the required NuGet packages and add the namespace to the page. To install Syncfusion Xamarin Toolbox, refer to Toolbox.

Method 3: Adding SfAvatarView assemblies manually from the installed location

If you prefer to manually reference the assemblies instead of referencing from NuGet, add the following assemblies in respective projects.

Creating an SfAvatarView control

The SfAvatarView control is configured entirely in C# or in XAML. The following steps explain how to create an SfAvatarView control and configure its elements.

Adding namespace for referred assemblies

[XAML]

xmlns:sfavatar="clr-namespace:Syncfusion.XForms.AvatarView;assembly=Syncfusion.Core.XForms"

Adding the SfAvatarView control as the content of ContentPage

You can add a custom image for displaying in SfAvatarView using the ImageSource property.

[XAML]

<ContentPage.Content>
<Grid>
    <sfavatar:SfAvatarView ContentType="Custom"
                           ImageSource="alex.png"
                           VerticalOptions="Center"
                           HorizontalOptions="Center"   
                           HeightRequest="50"
                           CornerRadius="25"
                           WidthRequest="50" />
</Grid>
</ContentPage.Content>

Bind staticresource to imagesource in SfAvatarView

[XAML]

 <ContentPage.Resources>
        <ResourceDictionary>
            <x:String x:Key="avatarImage">Avatar.png</x:String>
        </ResourceDictionary>
       
 </ContentPage.Resources>
    
    <Grid>
        <avatarView:SfAvatarView ContentType="Custom"
                           ImageSource="{Binding AvatarImage}"
                           VerticalOptions="Center"
                           HorizontalOptions="Center"   
                           HeightRequest="50"
                           CornerRadius="25"
                           WidthRequest="50" />
    </Grid>

View Model

[C#]

 public class AvatarViewModel : INotifyPropertyChanged
    {
        public event PropertyChangedEventHandler PropertyChanged;

        protected virtual void NotifyPropertyChanged([CallerMemberName] string propertyName = "")
        {
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
        }

        private ImageSource avatarImage = "Avatar.png";
        public ImageSource AvatarImage
        {
            get { return avatarImage; }
            set { avatarImage = value; }
        }
    }
