Assembly: System.Windows (in System.Windows.dll)
For other events that also use DragEventArgs the value of is not null. However, any attempt to call the IDataObject API on that object always raises a SecurityException. This ensures that only the drop target is permitted access to the data.
Type - typed format parameter APIs are not supported.
APIs that support automatic format conversion are not supported.
The data object is read-only to callers. Therefore, all signatures of SetData are not supported.
