Simple Example of Silverlight data binding (markup extension)

In this example, the bound data is an instance of the owner class. Now, an owner class is added to the Silverlight project.

Class owner

Public class owner
{
Public int ownerid {Get; set ;}
Public String firstname {Get; set ;}
Public String lastname {Get; set ;}
Public String address {Get; set ;}
Public String zipcode {Get; set ;}
Public String city {Get; set ;}
Public String state {Get; set ;}
Public String country {Get; set ;}
Public datetime birthdate {Get; set ;}
Public datetime customersince {Get; set ;}
Public String imagename {Get; set ;}
Public datetime lastactivitydate {Get; set ;}
Public double currentbalance {Get; set ;}
Public double lastactivityamount {Get; set ;}
}

 

 

Create an instance of the owner class in mainpage. XAML. CS.

 Mainpage. XAML. CS

Public Mainpage ()
{
Initializecomponent ();
Initializeowner ();
}

Private   Void Initializeowner ()
{
Owner =   New Owner ();
Owner. ownerid =   1234567 ;
Owner. firstname =   " Zhu " ;
Owner. lastname =   " JZ " ;
Owner. Address =   " Chaoyang BJ " ;
Owner. zipcode =   " 100001 " ;
Owner. City =   " Beijing " ;
Owner. Country =   " China " ;
Owner. State =   " Beijing " ;
Owner. imagename =   " Wo.jpg " ;
Owner. lastactivityamount =   100 ;
Owner. lastactivitydate = Datetime. today;
Owner. currentbalance =   1234.56 ;
Owner. Birthdate =   New Datetime ( 1986 , 6 , 8 );
Owner. customersince =   New Datetime ( 2009 , 12 , 20 );
}

 

 

 

By now, you have used the extended identity syntax (Markup Extension) Implements the text attribute bound to textblock. In the last step, bind the owner class instance to the control.CodeTo achieve:

PublicMainpage ()

{
Initializecomponent ();
Initializeowner ();
Ownerdetailsgrid. datacontext = Owner;
}

 

 

 The effect is as follows:

 

 

 

Let's look back at The XAML code. As mentioned above, textblock data binding is implemented through extended identifiers:

 <TextblockText="{Binding customersince}" />

 

In fact, this is an abbreviation. The complete binding syntax is as follows:

 <TargetcontrolTargetproperty="{Binding sourceproperty, somebindingproperties}" />
