I have WPF application and a window in it. Lets have something like this in my xml:
<Label Name="TitleLabel" Content="Some title" \>
<Label Name="BottomLabel" Content="{Binding ElementName=TitleLabel Path=Content">
Lets say I don't cannot use xml for creation of BottomLabel
and TitleLabel
. So I have to create the BottomLabel as a property in my "Code behind". How do I specify the same binding for Content
property of Bottom label in my code behind ? Is it possible at all ?
So I would have something like this:
public Label TitleLabel {get; private set;}
public Label BottomLabel {get; private set;}
public MyClass(){
TitleLabel = new Label();
TitleLabel.Content = "Some title";
BottomLabel = new Label();
BottomLabel.Content = // ?? what should be here ? How do I specify the binding
// that binds BottomLabel.COntent to TitleLabel.Content?
}
What can I write instead of the comment ? Thank you for ansvers.
Here's how you define and apply a binding in code:
Binding binding = new Binding {
Source = TitleLabel,
Path = new PropertyPath("Content"),
};
BottomLabel.SetBinding(ContentControl.ContentProperty, binding);
Note that on objects that don't derive from FrameworkElement
, you have to explicitly use BindingOperations.SetBinding()
instead of element.SetBinding()
:
BindingOperations.SetBinding(BottomLabel, ContentControl.ContentProperty, binding);
