Sir, In our software, we want to show peak information to user, No of Columns for General Info = 7 (Constant) No of Columns for Injection Info = 22 (Constant) No of Fixed Column(s) for Peak Info = 1(Constant) //It is for Peak Area Sum. Total No of Columns for N Peaks: N x (13 + 2 x N) Hence total Number of Columns in Datagrid in case of N Peaks = 1(Separator) + 7 + 1(Separator) + 22 + 1(Separator) + 1 + N(13+2N) = 2xNxN + 13xN + 33 Hence Number of Columns in the Datagrid increase as a 2nd Degree Equation. This means For 10 peaks Column Count will be 363 For 25 peaks Column Count will be 1608 For 50 peaks Column Count will be 5683 For 100 peaks Column Count will be 21333 For 150 peaks Column Count will be 46983 For 200 peaks Column Count will be 82633
