How to Style the TokenItem in WinUI AutoComplete

This article explains how to style the tokenitem in WinUI AutoComplete.

The AutoComplete control allows you to customize the style of the AutoCompleteTokenItem generated in the selection area using the TokenItemStyle property. The default value of TokenItemStyle is null.

XAML

<editors:SfAutoComplete 
   SelectionMode="Multiple"
   ItemsSource="{Binding SocialMedias}"
   DisplayMemberPath="Name"
   TextMemberPath="Name">
   <editors:SfAutoComplete.TokenItemStyle>
       <Style TargetType="editors:AutoCompleteTokenItem">
           <Setter Property="Foreground" Value="Red"/>
           <Setter Property="Background" Value="LightCyan"/>
       </Style>
   </editors:SfAutoComplete.TokenItemStyle>
</editors:SfAutoComplete>

Styling token items based on condition

The AutoComplete control allows you to customize the style of the AutoCompleteTokenItem conditionally based on their content using the TokenItemStyleSelector property. The default value of TokenItemStyleSelector is null.

C#

public class SocialMediaStyleSelector : StyleSelector
{
   public Style MediaStyle1 { get; set; }
   public Style MediaStyle2 { get; set; }
   public Style DefaultStyle { get; set; }
   protected override Style SelectStyleCore(object item, DependencyObject container)
   {
       if (item is SocialMedia)
       {
           var mediaItem = (item as SocialMedia).Name;
           if (mediaItem.ToString() == "Facebook" || mediaItem.ToString() == "Instagram" ||
               mediaItem.ToString() == "Twitter" || mediaItem.ToString() == "WhatsApp" ||
               mediaItem.ToString() == "Skype")
           {
               return MediaStyle1;
           }
           else
           {
               return MediaStyle2;
           }
       }
       return DefaultStyle;
   }
}

<Grid>
   <Grid.Resources>
       <Style x:Key="MediaStyle1" TargetType="editors:AutoCompleteTokenItem">
           <Setter Property="Foreground" Value="Blue"/>
           <Setter Property="Background" Value="LightCyan"/>
           <Setter Property="Content" Value="{Binding}"/>
       </Style>
       <Style x:Key="MediaStyle2" TargetType="editors:AutoCompleteTokenItem">
           <Setter Property="Foreground" Value="Red"/>
           <Setter Property="Background" Value="LightCyan"/>
           <Setter Property="Content" Value="{Binding}"/>
       </Style>
       <local:SocialMediaStyleSelector 
           x:Key="socialMediaStyleSelector" 
           MediaStyle1="{StaticResource MediaStyle1}"
           MediaStyle2="{StaticResource MediaStyle2}"/>
   </Grid.Resources>
   <editors:SfAutoComplete 
       SelectionMode="Multiple"
       ItemsSource="{Binding SocialMedias}"
       TokenItemStyleSelector="{StaticResource socialMediaStyleSelector}"
       DisplayMemberPath="Name"
       TextMemberPath="Name" />
</Grid>
