How to get DataContext for UIElement?

Question

As UIElement has no property DataContext, how can I get the DataContext for UIElement?

The DataContext property is introduced to the inheritance hierarchy in the FrameworkElement.

Because FrameworkElement inherits from UIElement you have to make sure the UIElement actually is a FrameworkElement:

if(uiElement is FrameworkElement frameworkElement)
{
    var dc = frameworkElement.DataContext;
}

You should be able to cast the UIElement to a FrameworkElement and then access the DataContext property.

With all due respect, this is not good advice. It is perfectly legal to create custom UI elements by deriving directly from `UIElement`, and this is perhaps even preferred if you want a lighter-duty control and/or don't need or want the additional layout and data-handling capabilities of `FrameworkElement`. Since the existence of non-FE controls can't be ruled out, "casting the `UIElement` to `FrameworkElement`" seems like shaky advice considering how little information was given by the OP. – Glenn Slayden Jun 29 '18 at 23:46
