Hi!!!
I have a data-table whose content are as

FnYear     || 1 || 2 || 3 || 4 || 5 || 6 || 7 || 8 || 9 || 10 || 11 || 12
 
2001-2002  || 8 || 8 || 8 || 8 || 8 || 8 || 9 || 9 || 9 || 9  || 9  || 9
2002-2003  || 8 || 8 || 8 || 8 || 8 || 8 || 8 || 8 || 8 || 8.60  || 8.60 || 8.60

Your question is far from clear. Where is this data, in a database, a file, memory? How are you trying to access it ...
Please think about what problem you are trying to solve before you write your question.

I have mentioned that data is in a datatable.

Philip Stuyck 3-Aug-12 9:38am

you mean you want to find out when 1 changes into 2, 2 into 3, ... for the first ow, and when 8 changes into 9 on the second row right ?
You must have some code, please show what you got already.

No. sorry for the ambiguous question. I need to find when 8 changes to 9 or 8 changes to 8.60. for example in fnYear 2001-2002 it changes at column name 7 and in 2002-2003 it changes at column name 10

I have taken all the values for a particular financial year into a list (of String) but after that i am stuck .what to do ??

Did you try using the Datatable.getchanges() method.

It gives us particular rows having pending changes. what i need is the column for a particular row. Say i have row with fnYear 2001-2002 then i need column Name 7 as result

Uh, am I missing something? This seems trivial.

int GetChangeIndex(DataRow row){
 double value = double.Parse(row.Cells[0].Value);
 
 for(int i = 1; i < row.Cells.Length; i++){
  double thiscell = double.Parse(row.Cells[i].Value);
  if(value != thiscell) return i;
  else value = thiscell;
 }

 return -1; // no change; you could also return
            // row.Cells.Length, or throw an exception
}
