How to: Create a Binding in Code
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 inherit either of those classes, you can call the SetBinding method directly, as in following example. In this example,
myDataObject is an instance of
MyData class and
myBinding is the source Binding object.
MyData class is a defined class that contains a string property named
MyDataProperty. The following example shows how to bind the text content of
mytext, an instance of TextBlock, to
//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.
Alternatively, you can use the SetBinding method of the BindingOperations class. In the following example,
myNewBindDef is a Binding object that describes the binding. The binding target is
myDateText, an instance of the TextBlock class.
