How to Style Token Item in WinUI ComboBox

This article explains how to style token items in WinUI ComboBox.

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

XAML

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

Style token items based on condition

The ComboBox control allows you to customize the style of ComboBoxTokenItem conditionally based on its 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; }
   protected override Style SelectStyleCore(object item, DependencyObject container)
   {
       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;
       }
   }
}

XAML

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