How to Customize the Editing TextBox in WinUI ComboBox?

This article explains the customization options available for the WinUI ComboBox control.

You can customize the appearance of the editable TextBox within the SfComboBox by using the TextBoxStyle property. By default, the TextBoxStyle property is set to null. Note that this property is effective only in single selection mode.

XAML:

<editors:SfComboBox x:Name="comboBox"
                   Width="250"
                   IsEditable="True"
                   SelectionMode="Single"
                   ItemsSource="{Binding SocialMedias}"
                   DisplayMemberPath="Name"
                   TextMemberPath="Name">
                   
   <editors:SfComboBox.TextBoxStyle>
       <Style TargetType="TextBox">                   
           <Style.Setters>              
               <Setter Property="SelectionHighlightColor" Value="Green"/>  
               <Setter Property="BorderThickness" Value="0"/> 
           </Style.Setters>
       </Style>
   </editors:SfComboBox.TextBoxStyle>
</editors:SfComboBox>
