Property Value

Type Default Description
DragDropMode Standard

A DragDropMode enumeration value.

Available values:

Name Description

This mode is suitable for single-thread applications. If this mode is enabled, all Drag~ events of the RichEditControl are correctly raised when objects are dragged and dropped.


This mode is suitable for mutli-thread applications, when no Drag~ events of the RichEditControl can be raised.


To enable RichEditControl’s drag-and-drop operation in a Multi Threaded Apartment (MTA), the DragDropMode property value should be set to DragDropMode.Manual. In this case, drag-and-drop events such as DragEnter, DragLeave, DragOver and DragDrop are not raised.


The Defauilt value of DragDropMode (the DragDropMode.Standard) in MTA state results in application failure.
