I am working on some drag and drop code.
When some data is moved over a target which accept it I want to show a data
preview.

For this I attempt to create an UIElement with the default DataTemplate.
Problem is, I don't know how to setup the UIElement returned by the
DataTemplate! (i.e. setup it binding correctly)

===== pseudo code: =======
IDataObject ido = ......;
object data = ido.GetData("some key");
FrameworkElement target = sender as FrameworkElement;
DataTemplate dt = target.FindResource(data.GetType()) as DataTemplate;
UIElement ui = dt.LoadContent() as UIElement;

// NOW HOW DO I SET UP DATA BINDING?
ui.....= .....
==================

PS: I do need to get the UIElement, as I measure it to position it
relatively to the mouse position.

Databinding in code is done using the Binding class:

There is an example here:

Is that what you're after?

HTH,

Not really, but....

1. thanks for answering
2. I found what I need:

--- get the data ---
IDataObject ido = ......;
object data = ido.GetData("some key");

--- show it with the default template ---
ContentControl c = new ContentControl();
c.Content = data;

c.Content could be anything, unlike what the documentation states (UIElement
or string)
