Hi. I have an ASP.Net GridView which contains textboxes. I am going to add footer where it contains the sum of the same column and at the end of each row also a sum field is there. The number of rows may be vary in different report, but the columns are fixed.
Here is the jsFiddle http://jsfiddle.net/dUa85/21/[^] where it contains the html output. I was able to get near to what i expected, but the keystrokes are also getting counted. Please try to add values under Jan textboxes to get the problem duplicated.

Any solution? If more details are needed, please let me know.

Thank you for your time.
