How to show the preview when I drag a block.

Hi all,

I want to show the preview of the block dragged. How to do that? Is it a Jig OR only show a thumbnail near the cursor? If possible, could you give me a sample? it is better C# not VB.net codes. Thanks in advanced!

Thanks,
Hongdan

Yes, I also use the way to create a EntityJig, but when I dragging a block(don't release the cursor) and make the Jig run, it will be crashed. And the error message is "eNotOpenForWrite". Do I need to save the drag block firstly and open it agian? If possible, could you give me a sample about it.

Thanks,
Hongdan.
