Hi,

I am using a XamRichTextEditor and a ListView whose items are draggable. I would like to insert a string in the document when the user drops an element on the XamRichTextEditor. For that, i use the DragSource and DropTarget elements from the Infragistics framework.

In the DragSource.Drop event handler, I can use the GetPosition() method on the DropEventArgs to get the Point where the Drop occured (relative to the XamRichTextEditor). My problem is that i can't find a way to get a DocumentOffset or a TextPosition or a TextRange for this Point that I could use to insert the text in the right place inside the document.

Is there a way to acheive this ?

Note: the WinRT native ITextDocument has a GetRangeFromPoint method that does just that and works perfectly.

Note 2: The WPF native RichTextBox has a GetPositionFromPoint method that does just that and also works perfectly. Unfortunatly I can't use the native RichTextBox control because its support for some advanced Rtf formatting options is not good enough for what i want to achieve and the XamRichTextEditor seems to handle them better.

Thank you for your help.
