ComboBox supports a cellFactory which allows essentially an arbitrary UI for displaying the item in each cell. ChoiceBox does not have this functionality and will only display text in each cell (which you can configure using a converter).

Try this <Window.Resources> //Put this resourse n Window.Resources or UserControl.Resources <LinearGradientBrush x:Key=”NormalBrush” StartPoint=”0,0″ EndPoint=”0,1″> <GradientBrush.GradientStops> <GradientStopCollection> <GradientStop Color=”#FFDC3939″ Offset=”0.0″/> <GradientStop Color=”#FFE80E0E” Offset=”1.0″/> </GradientStopCollection> </GradientBrush.GradientStops> </LinearGradientBrush> <SolidColorBrush x:Key=”WindowBackgroundBrush” Color=”#FFFBE618″ /> <ControlTemplate x:Key=”ComboBoxToggleButton” TargetType=”ToggleButton”> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition /> <ColumnDefinition Width=”20″ /> </Grid.ColumnDefinitions> <Border x:Name=”Border” Grid.ColumnSpan=”2″ CornerRadius=”2″ Background=”{StaticResource NormalBrush}” BorderThickness=”1″ /> <Border Grid.Column=”0″ CornerRadius=”2,0,0,2″ Margin=”1″ Background=”{StaticResource WindowBackgroundBrush}” BorderThickness=”0,0,1,0″ … Read more

You can do this yourself by setting the DataTemplate of the combo box. This article shows you how – for a listbox, but the principle is the same. Another article here is perhaps a better fit for what you are trying to do, simple set the first column of the item template to be a … Read more

Define a class public class Language { public string Name { get; set; } public string Value { get; set; } } then… //Build a list var dataSource = new List<Language>(); dataSource.Add(new Language() { Name = “blah”, Value = “blah” }); dataSource.Add(new Language() { Name = “blah”, Value = “blah” }); dataSource.Add(new Language() { Name … Read more
