I have NetAdvantage for Windows Forms 2011 Vol. 1 Complete Bundle but still i am getting the following error message with using Infragistics3.Documents.Excel.v11.1.dll
Error Messgae:- {"The formatted string is already the value of another cell or shape. Clone it first and apply the clone to the new cell or shape."}
As per the below forum, this issue was already fixed in version 7.3 http://community.infragistics.com/forums/p/6191/26845.aspx
Hello,
I tried this and it always works fine for me so I attached my sample to this post for you. Please review it and feel free to let me know if I misunderstood you or if you have any other questions.
