Body
You are referring to a situation similar to delete-on-paste in Windows Explorer where a file is not deleted from the source folder until a Paste operation occurs. <a href="http://msdn.microsoft.com/en-us/library/bb776904(VS.85).aspx#delete_on_paste" rel="nofollow">http://msdn.microsoft.com/en-us/library/bb776904(VS.85).aspx#delete_on_paste</a> <h3>Easy Answer</h3> If you are doing this within the same instance of the application, then this is referred to an optimized move where you can simply set a local flag (such as a boolean variable) to determine if it was successful. Update: Yes, you can also check the results of the DoDragDrop method to determine if the drop was successful. Just make sure that your drop-handling code properly sets the Effect to None if there was an error completing the drop, or else your code with DoDragDrop will think that the drop was a success. This method will even work between two instances of your application. <h3>Hard Answer</h3> If you are doing this between two instances of your application, and you need to transfer more information that just whether or not the drop was successful, then you need to implement the OLE version of <code>IDataObject</code> so that the application instance that is the drop target completes the drag and drop, it can call SetData on the source object to send result information. This is complicated to do but is certainly possible. For more information on doing this, see these links: <a href="http://msdn.microsoft.com/en-us/library/system.runtime.interopservices.comtypes.idataobject.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/system.runtime.interopservices.comtypes.idataobject.aspx</a> <a href="http://blogs.msdn.com/b/delay/archive/2009/10/26/creating-something-from-nothing-developer-friendly-virtual-file-implementation-for-net.aspx" rel="nofollow">http://blogs.msdn.com/b/delay/archive/2009/10/26/creating-something-from-nothing-developer-friendly-virtual-file-implementation-for-net.aspx</a>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
