You should proably just bind the text attribute of the TextBlock to the selected item of the list box. Check this article at MSDN.

 <StackPanel>
    <TextBlock Width="248" Height="24" Text="Colors:" 
        TextWrapping="Wrap"/>
    <ListBox x:Name="lbColor" Width="248" Height="56">
        <ListBoxItem Content="Blue"/>
        <ListBoxItem Content="Green"/>
        <ListBoxItem Content="Yellow"/>
        <ListBoxItem Content="Red"/>
        <ListBoxItem Content="Purple"/>
        <ListBoxItem Content="Orange"/>
    </ListBox>
    <TextBlock Width="248" Height="24" Text="You selected color:" />
    <TextBlock Width="248" Height="24">
        <TextBlock.Text>
            <Binding ElementName="lbColor" Path="SelectedItem.Content"/>
        </TextBlock.Text>
    </TextBlock>
</StackPanel>

        string sql = "Select * from Dictionary";
        OleDbCommand cmd = new OleDbCommand(sql, con);
        OleDbDataAdapter da = new OleDbDataAdapter(cmd);
        DataSet ds = new DataSet();
        try

            listBox1.ItemsSource = view;


        }
        catch (Exception ex)
        { 




        }}

    private void textBox1_TextChanged(object sender, TextChangedEventArgs e)
        {

            view.RowFilter = string.Format("Name Like '{0}%'", textBox1.Text);

    }







}

}

            <DataTemplate>

                <TextBlock Text="{Binding Path=Name}"> </TextBlock>
            </DataTemplate>



        </ListBox.ItemTemplate>
    </ListBox>

    <TextBox Height="23" Margin="18,40,0,0" Name="textBox1" VerticalAlignment="Top" TextChanged="textBox1_TextChanged" HorizontalAlignment="Left" Width="213" />
    <TextBlock HorizontalAlignment="Right"  Margin="0,77,42,83" Name="textBlock1" Width="185" Background="#FFE6C6C6" /><Label Height="28"  HorizontalAlignment="Right" Margin="0,39,76,0" Name="label1" VerticalAlignment="Top" Width="140">Label</Label>
