How to: Create a Binding in Code
This example shows how to create and set a xref:System.Windows.Data.Binding in code.
Example
The xref:System.Windows.FrameworkElement class and the xref:System.Windows.FrameworkContentElement class both expose a SetBinding method. If you are binding an element that inherits either of these classes, you can call the xref:System.Windows.FrameworkElement.SetBinding%2A method directly.
The following example creates a class named, MyData, which contains a property named MyDataProperty.

The following example shows how to create a binding object to set the source of the binding. The example uses xref:System.Windows.FrameworkElement.SetBinding%2A to bind the xref:System.Windows.Controls.TextBlock.Text%2A property of myText, which is a xref:System.Windows.Controls.TextBlock control, to MyDataProperty.

For the complete code sample, see Code-only Binding Sample.
Instead of calling xref:System.Windows.FrameworkElement.SetBinding%2A, you can use the xref:System.Windows.Data.BindingOperations.SetBinding%2A static method of the xref:System.Windows.Data.BindingOperations class. The following example, calls xref:System.Windows.Data.BindingOperations.SetBinding%2A?displayProperty=nameWithType instead of xref:System.Windows.FrameworkElement.SetBinding%2A?displayProperty=nameWithType to bind myText to myDataProperty.
