Silverlight data binding-element property binding

For programmers, a lot of knowledge is better explained by code than by text. So when introducing the Silverlight data binding feature, I use the following code as a memorandum for future study ......

Don't try it on the masses ......

 1:  <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">

 2:              <Grid.RowDefinitions>

 3:                  <RowDefinition Height="*" />

 4:                  <RowDefinition Height="*" />

 5:                  <RowDefinition Height="*" />

 6:              </Grid.RowDefinitions>

 7:  

 8:              <Slider Name="slider" 

 9:  Value="90"

10:  Grid.Row="0"

11:  Maximum="180"

12:  Margin="24" />

13:  

14:              <TextBlock Name="txtblk" 

15:  Text="{Binding ElementName=slider, Path=Value}"

16:  Grid.Row="1"

17:  FontSize="48"

18:  HorizontalAlignment="Center"

19:  VerticalAlignment="Center" />

20:  

 

Note that the text binding code of the textbock attribute in the above Code can also be simplified in the following form: text = "{binding value, elementname = slider }".

You can also use the following alternative code: text = "{binding elementname = contentpanel, Path = children [0], value }".

It is worth noting that this binding syntax can be used without the attribute element Syntax:

 1:   <TextBlock Name="txtblk" 

 2:  Grid.Row="1"

 3:  FontSize="48"

 4:  HorizontalAlignment="Center"

 5:  VerticalAlignment="Center" >

 6:                  <TextBlock.Text>

 7:                      <Binding ElementName="slider" Path="Value"></Binding>

 8:                  </TextBlock.Text>

 9:              </TextBlock>

10:  

11:  

 

Silverlight Data Binding can also use C # code. Of course, it is also easy to ignore or use less, but it should also be paid attention!

 1:  using System;

 2:  using System.Collections.Generic;

 3:  using System.Linq;

 4:  using System.Net;

 5:  using System.Windows;

 6:  using System.Windows.Controls;

 7:  using System.Windows.Documents;

 8:  using System.Windows.Input;

 9:  using System.Windows.Media;

10:  using System.Windows.Media.Animation;

11:  using System.Windows.Shapes;

12:  using Microsoft.Phone.Controls;

13:  using System.Windows.Data;

14:   

15:  namespace SliderBindings

16:  {

17:      public partial class MainPage : PhoneApplicationPage

18:  {

19:          // Constructor

20:  public MainPage()

21:          {

22:              InitializeComponent();

23:              Binding binding = new Binding();

24:              binding.ElementName = "slider";

25:              binding.Path = new PropertyPath("Value");

26:              //1.this.txtblk.SetBinding(TextBlock.TextProperty,binding);

27:              //2.BindingOperations.SetBinding(this.txtblk,TextBlock.TextProperty,binding);

28:  }

29:      }

30:  }

The code above binds the attribute value of the silder element named slider with the attribute text of the textblock element named txtblk ......
