  • Hi David

     

    If you want binding in xaml then please write code as following

     

    <ComboBox Height="34" Margin="52,25,20,0"  Name="comboBox1"

                      VerticalAlignment="Top" >

                <ComboBoxItem >Item1</ComboBoxItem>

                <ComboBoxItem >Item2</ComboBoxItem>

                <ComboBoxItem >Item3</ComboBoxItem>

            </ComboBox>

            <TextBox Height="31" Text="{Binding ElementName=comboBox1,Path=SelectionBoxItem, Mode=OneWay}" Margin="54,93,22,0" Name="textBox1" VerticalAlignment="Top" />
