DisallowDrop Property

Returns or sets a boolean value indicating whether the drag/drop operation should be explicitly disallowed.

Syntax

Visual Basic

'Declaration
 
Public Property DisallowDrop As Boolean

C#

public bool DisallowDrop {get; set;}

Remarks

Use this property to cancel the drag/drop operation that is currently in progress.

Because the dragged data may be incompatible with the drop location, a drag/drop operation cannot be explicitly allowed; as such, setting this property to false has no effect.

When this property is set to true, the DropAreaDragDrop event does not occur.
