.NET Framework Class Library
FrameworkElementSetBinding Method (DependencyProperty, BindingBase)

Attaches a binding to this element, based on the provided binding object.

Namespace:   System.Windows
Assembly:  PresentationFramework (in PresentationFramework.dll)
Public Function SetBinding ( _
	dp As [%$TOPIC/ms598273_en-us_VS_110_1_0_0_0_0%], _

Type: System.WindowsDependencyProperty

Identifies the property where the binding should be established.

Type: System.Windows.DataBindingBase

Represents the specifics of the data binding.

Return Value

Type: System.Windows.DataBindingExpressionBase
Records the conditions of the binding. This return value can be useful for error checking.

This method is a convenience method for calling BindingOperationsSetBinding, which passes the current instance as the DependencyObject.


This example shows how to create and set a Binding in code.

The FrameworkElement class and the FrameworkContentElement class both expose a SetBinding method. If you are binding an element that inherits either of these classes, you can call the SetBinding method directly.

The following example creates a class named, MyData, which contains a property named MyDataProperty.

Public Class MyData
    Implements INotifyPropertyChanged

    ' Events 
    Public Event PropertyChanged As PropertyChangedEventHandler _
        Implements INotifyPropertyChanged.PropertyChanged

    ' Methods 
    Public Sub New()
    End Sub 

    Public Sub New(ByVal dateTime As DateTime)
        Me.MyDataProperty = ("Last bound time was " & dateTime.ToLongTimeString)
    End Sub 

    Private Sub OnPropertyChanged(ByVal info As String)
        RaiseEvent PropertyChanged(Me, New PropertyChangedEventArgs(info))
    End Sub 

    ' Properties 
    Public Property MyDataProperty As String 
            Return Me._myDataProperty
        End Get 
        Set(ByVal value As String)
            Me._myDataProperty = value
        End Set 
    End Property 

    ' Fields 
    Private _myDataProperty As String 
End Class
public class MyData : INotifyPropertyChanged
    private string myDataProperty;

    public MyData() { }

    public MyData(DateTime dateTime)
        myDataProperty = "Last bound time was " + dateTime.ToLongTimeString();

    public String MyDataProperty
        get { return myDataProperty; }
            myDataProperty = value;

    public event PropertyChangedEventHandler PropertyChanged;

    private void OnPropertyChanged(string info)
        PropertyChangedEventHandler handler = PropertyChanged;
        if (handler != null)
            handler(this, new PropertyChangedEventArgs(info));

The following example shows how to create a binding object to set the source of the binding. The example uses SetBinding to bind the Text property of myText, which is a TextBlock control, to MyDataProperty.

Dim data1 As New MyData(DateTime.Now)
Dim binding1 As New Binding("MyDataProperty")
binding1.Source = data1
Me.myText.SetBinding(TextBlock.TextProperty, binding1)
//make a new source
  MyData myDataObject = new MyData(DateTime.Now);      
  Binding myBinding = new Binding("MyDataProperty");
  myBinding.Source = myDataObject;
  myText.SetBinding(TextBlock.TextProperty, myBinding);

For the complete code sample, see Code-only Binding Sample.

Instead of calling SetBinding, you can use the SetBinding static method of the BindingOperations class. The following example, calls BindingOperationsSetBinding instead of FrameworkElementSetBinding to bind myText to myDataProperty.

Dim myDataObject As New MyData(DateTime.Now)
Dim myBinding As New Binding("MyDataProperty")
myBinding.Source = myDataObject
BindingOperations.SetBinding(myText, TextBlock.TextProperty, myBinding)
//make a new source
MyData myDataObject = new MyData(DateTime.Now);
Binding myBinding = new Binding("MyDataProperty");
myBinding.Source = myDataObject;
BindingOperations.SetBinding(myText, TextBlock.TextProperty, myBinding);
