Hi,

Is it possible to drag from a TreeView to an excel worksheet where the
TreeView was spawned from a click event on a command bar button ? The command
bar is created by a VSTO app-level add-in. We are using C#.

More specifically, the nodes in the TreeView represent Reports that would
appear in the Excel worksheet after they are dragged into it. (We do not want
to use an actions pane because we need the TreeView to be application level
and we have to make it work in Excel 2003 -- which does not support app-level
actions panes or app-level Custom Task Panes). So there are really 2
questions he

1) How do we accomplish the drag drop operation in this scenario ?
Especially the drop part.

2) How do we recognize the drop target in such a way that we can read a
bunch of metadata (containing cell contents) from perhaps an XML file or some
other file to create the report in the Excel spreadsheet ?

Is this a dream or can it actually be done ?

We greatly appreciate any guidance you could provide.

Thanks,

Kinda surprised nobody responded, but I found this article quite helpful:

The one thing missing is I don't know what Excel event to use if there is no
workbook open. The SheetChange event covers the case when there is a workbook
open.
