Como: Criar uma ligação simples

  • Artigo

This example shows you how to create a simple Binding.

Exemplo

In this example, you have a Person object with a string property named PersonName. The Person object is defined in the namespace called SDKSample.

The following example instantiates the Person object with a PersonName property value of Joe. This is done in the Resources section and assigned an x:Key.

<Window
  xmlns="https://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="https://schemas.microsoft.com/winfx/2006/xaml"
  xmlns:src="clr-namespace:SDKSample"
  SizeToContent="WidthAndHeight"
  Title="Simple Data Binding Sample">

  <Window.Resources>
    <src:Person x:Key="myDataSource" PersonName="Joe"/>


...


</Window.Resources>


...


</Window>

To bind to the PersonName property you would do the following:

<TextBlock Text="{Binding Source={StaticResource myDataSource}, Path=PersonName}"/>

As a result, the TextBlock appears with the value "Joe".
