@Dhananjay The question is posted in ASP.NET & Web Development category hence the Windows Forms solution is not going to be much helpful I believe.

static void Main() { Console.Write(Enter number of rows of matrix (max 18) : ); int numRows = int.Parse(Console.ReadLine()); Console.Write(Enter number of columns of matrix (max 18) : ); int numCols = int.Parse(Console.ReadLine()); Console.WriteLine(Enter elements of the matrix (integers only)
); // allow an extra row and column for the sums int[] m = new int[numRows + 1 numCols + 1]; for(int i = 0; i { for(int j = 0; j { Console.Write( Row {0} Col {1} :  i + 1 j + 1); m[i j] = int.Parse(Console.ReadLine()); m[i numCols] += m[i j]; m[numRows j] += m[i j]; m[numRows numCols] += m[i j]; } } // display results Console.WriteLine(); Console.Write(R/C ); for(int i = 0; i Console.WriteLine( Sum); Console.WriteLine(new string ('-' 4 * numCols + 8)); for (int i = 0; i { if (i if (i == numRows) { Console.WriteLine(new string ('-' 4 * numCols + 8)); Console.Write(Sum ); } for(int j = 0; j { Console.Write( {0 2}  m[i j]); } Console.WriteLine(); } Console.ReadKey(); }

I am not an expert on the subject but from whatever knowledge I have... You can place the label controls in the above grid wherever you wish to show totals. Make sure they have id attribute added. Furthermore hopefully you have generated unique id attribute to each text box in a systematic way for example txtAmount0000 where first two 0s indicate row and next two 0s indicate column etc. You can then call a function may be refreshTotal() in change event of each text box. In the function do the total and show in label control with the help of id. Don't worry about which text box changed. Just total and show!
