Thanks for the info.
I wouldn't expect the ganttview to have any complicated export to excel/word. It would just be nice to have export features like the RadChart has - where you can export it to excel (basically insert it in excel as an image), pdf, or png/bmp. Basically it would be nice to have .ExportToImage(stream, encoder) and .ExportToExcelML(stream) methods. Word isn't that important, but it would be nice to export the image into word like it is done in excel.
Another thing that might be nice would be to include or exclude the table in the export. (and also when printing) Sometimes the user might just want print/export the gantt chart, and hide the table columns when printing/exporting. I've used RadiantQ's gantt control before(http://demos.radiantq.com/silverlight/
) --in terms of ease of use and performance, Telerik's gantt is way better, even in its early stage. (kudos to you!) RadiantQ provides an export to image (png/bmp), and have examples of how to export just the table, just the chart, or both. (if you go to the URL, its under "Common", click on "ImageExport")
