Here we will just work out a simple way to display a selected item in a combo box using data binding method.
This is all done with XAML without using code behind.
MainWindow.xaml<Window x:Class="ComboBox2.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <StackPanel Margin="20,20,20,20"> <ComboBox Name="cbox" Text="My Cities" IsEditable="True" IsReadOnly="True"> <ComboBoxItem>Spain</ComboBoxItem> <ComboBoxItem>France</ComboBoxItem> <ComboBoxItem>Peru</ComboBoxItem> <ComboBoxItem>Mexico</ComboBoxItem> <ComboBoxItem>Italy</ComboBoxItem> </ComboBox> <TextBlock Text="{Binding ElementName=cbox, Path=SelectedItem.Content}" Width="200" Height="30" HorizontalAlignment="Center" Margin="10,100,50,50"></TextBlock> </StackPanel> </Window>
