How to bind a Control.Property to a property in the code-behind?

问题

I have a TextBox in my WPF window.

I have a property in the code behind called Text as well.

I want the text property to be bound to the Text property (i.e. when the value changes in the property the textbox value should also be updadated.

Thanks

You have to set the DataContext of the TextBox control (or of any of its parents) to your window:

myTextBox.DataContext = this;

then in your XAML:

<TextBox Text={Binding Text} x:Name="myTextBox"/>
