 Value Row Column 21 R5 C1 22 R3 C2 23 R4 C3 24 R2 C4 25 R1 C5 

Can anyone please help me, how should i achieve result?

Answer 1

Assuming column names are C1, C2, C3, C4, C5.

Pseudo code/Algorithm.

int C1_MaxValue, C2_MaxValue, C3_MaxValue, C4_MaxValue, C5_MaxValue;
string C1_Row, C2_Row, C3_Row, C4_Row, C5_Row;

//Initialize row1 values as max values.
C1_MaxValue = DataTable.Rows[1]["C1"];
C2_MaxValue = DataTable.Rows[1]["C2"];
C3_MaxValue = DataTable.Rows[1]["C3"];
C4_MaxValue = DataTable.Rows[1]["C4"];
C5_MaxValue = DataTable.Rows[1]["C5"];

//Set R1 as row for max values.
C1_Row = C2_Row = C3_Row = C4_Row = C5_Row = DataTable.Rows[1][Row1];

For (i=2 to RowCount -1)

 if(Datatable.Rows[i]["C1"] > C1_MaxValue) 
 {       
      C1_MaxValue = Datatable.Rows[i][C1]; 
      C1_Row = Datatable.Rows[i][0];
 }
 //Do the above for all other columns.
End For

At the end of this for the above variables should contain the max values and corresponding max rows.
