Hi,
I have an array of integers
I like to retrieve the max number and index of max number from that array without using Math.Max() function..
Presently in this below code, I have 4 dynamic values, end user will be select degree from combo box, entering the values semester, Max marks and Obtained marks as numeric values. Once entered dynamic rows will be created and it also calculate the percentage by the formula (om/mm)*100 for each row on clicking Sum and it also creates new column…
I needed to have code when the degree changes only.. it should calculate the sum of all max.marks and Obtained marks of each semester and then calculate percentage by above formula… and also new column should not be created…..Please sort with max marks… Please help me in this regard… Thank you for helping me initially.
what is the easiest way...
Cheers
Santhosh
