Multiplication and Sum in GridView ASP.Net C#

I have a datatable which is bound to GridView datasource as follows.
Overall i want to Multiply 'Quantity' column value with 'Part1 qty' column value until 'column5' cell value is repeating and so on
the result of operation should appear underneath the value as highlighted in red for understanding
My GridView data currently
I want the following output
Required Output

What I have done so far is
protected void GridView1_DataBound(object sender, EventArgs e)
{
int gridViewCellCount = GridView1.Rows[0].Cells.Count;
string[] columnNames = new string[gridViewCellCount];
for (int k = 0; k < gridViewCellCount; k++)
{
columnNames[k] = ((System.Web.UI.WebControls.DataControlFieldCell)(GridView1.Rows[0].Cells[k])).ContainingField.HeaderText;
}
for (int i = GridView1.Rows.Count - 1; i > 0; i--)
{
GridViewRow row = GridView1.Rows[i];
GridViewRow previousRow = GridView1.Rows[i - 1];
var result = Array.FindIndex(columnNames, element => element.EndsWith("QTY"));
var Arraymax=columnNames.Max();
int maxIndex = columnNames.ToList().IndexOf(Arraymax);
decimal MultiplicationResult=0;
int counter = 0;
for (int j = 8; j < row.Cells.Count; j++)
{
if (row.Cells[j].Text == previousRow.Cells[j].Text)
{
counter++;
if (row.Cells[j].Text != " " && result < maxIndex)
{
var Quantity = GridView1.Rows[i].Cells[1].Text;
var GLQuantity = GridView1.Rows[i].Cells[result].Text;
var PreviousQuantity= GridView1.Rows[i-1].Cells[1].Text;
var PreviousGLQuantity= GridView1.Rows[i-1].Cells[result].Text;
//var Quantity = dt.Rows[i].ItemArray[1];
//var GLQuantity = dt.Rows[i].ItemArray[Convert.ToInt64(result)].ToString();
var GLQ = GLQuantity.TrimEnd(new Char[] { '0' });
var PGLQ = PreviousGLQuantity.TrimEnd(new char[] { '0' });
if (GLQ == "")
{
GLQ = 0.ToString();
}
if (PGLQ == "")
{
PGLQ = 0.ToString();
}
MultiplicationResult = Convert.ToDecimal(Quantity) * Convert.ToDecimal(GLQ) + Convert.ToDecimal(PreviousQuantity) * Convert.ToDecimal(PGLQ);
object o = dt.Rows[i].ItemArray[j] + " " + MultiplicationResult.ToString();
GridView1.Rows[i].Cells[j].Text = o.ToString();
GridView1.Rows[i].Cells[j].Text.Replace("\n", "<br/>");
result++;

Windows Forms freezes and don't answer

My lab is about schedule and I use modified Kron algorithm.
When the button presses the form should print information on 4 richBoxes.
Sometimes everything is OK but sometimes the form freezes and don't answer. If I open the Task Manager window I see that my app takes about 30% CPU. Maybe it's because of cycle in the button? Maybe I should do more buttons? Or what? I don't understand..
So what's the prob?

Why Is This Code Running Longer Character Combinations Than Necessary?

I'm a math student with little to no experience programming, but I wrote this to act like a brute force algorithm. It seems to run fine except that it runs all the password combinations out to 3 characters for passwords as short as 2. Also I'm sure there's a way to refactor the for and if statements as well. Any help would be appreciated, thanks.
I've already been testing to see if some of the if statements aren't executing, and it looks like the statements with "console.writeln(Is this executing)" aren't executing but I'm not really sure.

Field methods in C# in the namespace

So the goal of my code is to pick two points in a grid of numbers and figure out with point gets the highest value of numbers when counting every other point in the grid closest to the two points. While typing this code I was trying to use private field variables to hold the current position of both pointers however I receive errors for the field variables I have and any calls that I make into this grid built.
namespace Program
{
private int xMe;
private int yMe;
private int zMe;
private int xEn;
private int yEn;
private int zEn;
private int dif = 0;
public class Castles
{
public static string Process(uint[,] grid)
{
int taxX = 0;
int taxY = 0;
for (int i = 0; i < grid.GetLength; i++)
{
for(int j = 0; j < grid[i]; j++)
{
for(int k = 0; k < grid.GetLength; k++)
{
for(int l = 0; l < grid[k]; l++)
{
if (distance(i, j, k, l) > 3)
{
if (grid[i, j] != 0 && grid[k, l] != 0)
{
for (int m = 0; grid.GetLength; m++)
{
for (int n = 0; grid[m]; n++)
{
if (grid[i, j] != grid[m, n] || grid[k, l] != grid[m, n])
{
if(distance(i,j,m,n) > distance(m, n, k, l))
{
taxX = taxX + distance[m, n];
}
else if(distance(i,j,m,n)< distance(m, n, k, l))
{
taxY = taxY + distance[m, n];
}
else
{
}
}
}
}
if(taxX - taxY > dif)
{
xMe = i;
yMe = j;
xEn = k;
yEn = l;
zMe = taxX;
zEn = taxY;
dif = taxX - taxY;
}
}
}
}
}
}
}
return "Your castle at (" + xMe + "," + yMe + ") earns " + zMe + ". Your nemesis' castle at (" + xEn + "," + yEn + ") earns " + zEn + ".";
}
public int distance(int x, int y, int a, int b)
{
int c = a - x;
int d = b - y;
return Math.Sqrt(c ^ 2 + d ^ 2);
}
static void Main(string[] args)
{
System.Console.WriteLine("");
}
}
}
This is my first exploration into c# so this could be a simple fix but any help would be useful

Just move the definitions of the fields to the inside of the class definition...

Weather Tracking Application

The Application has to display temperatures for five cities. I can't get the lowest and highest temperature columns to display. I got the first three columns for the temperature readings to display along with the average temperature column, but can't get the fourth temperature reading column to display. In addition, I can't get the area average label to display the area average. Any ideas?
