Data Table input

[AsianHaxer01]

I have a datatable generated whenever i open up a windows form and it loads correctly however, the user needs to be able to change the information within the text boxes and i want the information to save so i create a button on form that when clicked i want it to take in all the current data table information that currently exists compared to the previous information that used to be there. How do i take in the new information that exists in the data table?

I have tried

info.Clear(); //info is a string list
for (int i = 0; i < objectNum.Count - 1; i++)//retakes datatable info
{
for(int a = 0; a < 4; a++)
{
info.Add(d.Rows[a][i].ToString());//should add the row value
}
}

however it isn't working

any help would be great.
Thanks

if you need the .cs or the program please just leave a comment and ill add it

I found out my problem. Apparently i mixed up my x and y coordinates for the table which screwed up my calculations
