Thanks for the reply "Tony".
I have gone through the NodeXL Control. I have also drawn some sample graph reading data from excel and also from database. It works great.
I am just curious to use the Taskpane provided in source code of Excel Template inside c# panel with out ribbon and workbook.
Even if i start using NodeXL Control i think i end up making some user control similar to that TaskPane.So, i thought utilizing that Taskpane might save some time. What you say? :-)
Thanks once again.
