Hi..........
I created a web page using ext.net. In that page, I included a table which contains a grid panel with the columns id, name, salary and designation....
While i'm Exporting data into the excel sheet or open office.Org Calc, im getting an extra column with negative id values starting from -10..
I also verified the demo version present in ext.net----> demos---> Grid Panel--->Miscellaneous---->Export data postback. in that trial also it is generating a column with negative id values.....

Why is it happening??? Is it a problem with open office or a problem in design?????

If any one has an answer regarding this, reply me...

Thank you........
