How to use LongBindingPath in WPF

This article will describe for you how to use LongBindingPath using WPF. This is small example but very useful in WPF.

First of all make a new WPF application and add a new page using "Add New Item" then drag and drop some controls onto page. I have added one list box with a few listboxitems and I have added a textbox and lables. When we select any item of listbox the selected value will show in label.

Content="{Binding ElementName=TestPage, Path=Content.Children[1].SelectedItem.Content}">

Here is my full .xaml code

<Page x:Class="WPFBinding.Page1"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

mc:Ignorable="d" FontSize="14pt" Name="TestPage">

</ListBox>

</TextBlock>

</StackPanel>

</Page>

So when you run the application.
