Public Property DragDropMode As DragDropMode

Property Value

Type	Default	Description
DragDropMode	Standard	A DragDropMode enumeration value.

Available values:

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

Remarks

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.

Note

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