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

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 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();

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.

Play with this; modified from my answer here. It'll show you all the 2 and 3 length combinations. Clicking the button will start/stop the generation process. You need a button, label, and a timer:
public partial class Form1 : Form
{
private Revision rev;
public Form1()
{
InitializeComponent();
rev = new Revision("0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!? *-+", "00");
label1.Text = rev.CurrentRevision;
}
private void button1_Click(object sender, EventArgs e)
{
timer1.Enabled = !timer1.Enabled;
}
private void timer1_Tick(object sender, EventArgs e)
{
rev.NextRevision();
if (rev.CurrentRevision.Length == 4)
{
timer1.Stop();
MessageBox.Show("Sequence Complete");
// make it start back at the beginning?
rev = new Revision("0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!? *-+", "00");
label1.Text = rev.CurrentRevision;
}
else

i want create search in form similar EXCEL , find and put (row) in listview
this my form :
and my code :
private int searchIndex = -1;
private void button1_Click(object sender, EventArgs e)
{
button1.Text = "Find Next";
try
{
for (int i = 0; i < dataGridView1.Rows.Count; i++)
{
searchIndex = (searchIndex + 1) % dataGridView1.Rows.Count;
DataGridViewRow row = dataGridView1.Rows[searchIndex];
if (row.Cells["Product"].Value == null)
{
continue;
}
if (row.Cells["Product"].Value.ToString().Trim().StartsWith(textBox1.Text) || row.Cells["Product"].Value.ToString().Trim().Contains(textBox1.Text))
{
ListViewItem lvi = new ListViewItem(row.Cells["Product"].Value.ToString());
lvi.SubItems.Add(row.Cells["Product"].Value.ToString());
listView1.Items.Add(lvi);
dataGridView1.CurrentCell = row.Cells["Product"];
dataGridView1.FirstDisplayedScrollingRowIndex = dataGridView1.Rows[row.Index].Index;
row = dataGridView1.Rows[i];
return;
}
}
}
catch { }
}
and in textbox1_textchanged :
searchIndex = -1;
button1.Text = "Find";
listView1.Clear();
I want when search end, send message ...
thanks
Mimicking the Find All functionality, populating your ListView will be very similar to the Find Next functionality. Here's an example if it were a separate button from Find Next:
public Form1()
{
InitializeComponent();
listView1.View = View.Details;
listView1.Columns.Add("Column");
listView1.Columns.Add("Row");
listView1.Columns.Add("Value");
}
private void button2_Click(object sender, EventArgs e)
{
button2.Text = "Find All";
int tempIndex = -1;
listView1.Items.Clear();
for (int i = 0; i < dataGridView1.Rows.Count; i++)
{
tempIndex = (tempIndex + 1) % dataGridView1.Rows.Count;
DataGridViewRow row = dataGridView1.Rows[tempIndex];
if (row.Cells["Foo"].Value == null)
{
continue;
}
if (row.Cells["Foo"].Value.ToString().Trim().StartsWith(textBox1.Text) || row.Cells["Foo"].Value.ToString().Trim().Contains(textBox1.Text))
{
DataGridViewCell cell = row.Cells["Foo"];
ListViewItem lvRow = new ListViewItem(new string[] { cell.ColumnIndex.ToString(), cell.RowIndex.ToString(), cell.Value.ToString() });
listView1.Items.Add(lvRow);
}
}
MessageBox.Show("Search ended."); // Or whatever message you intend to send.

I am working on a project.I am creating an asp table dynamically and in table cell I am adding link button depending on condition.But while adding the Click event to link button it is giving an error saying-
System.Web.UI.WebControls.LinkButton.OnClick(System.EventArgs)' is inaccessible due to its protection level
Following is my code of making the table

string endday = enddate.DayOfWeek.ToString();//like saturday is 6,stating is from monday with 1 and ending si sunday with 7
int enddayno = Convert.ToInt32(enddate.DayOfWeek);
//for prevoius month

Please help how I can solve this problem
Correct subscription should look like this:
lnkevent.Click += test;
OnClick is a method used internally inside the class to raise the event. On the contrary you should be subscribing to the event itself.
I have a method that creates textboxes depending on the number of parameters values that the user has to enter.And its working fine. The problem is that when the user clicks Ok i want to take the value that the user entered in these textboxes and replace them in a string.

Please help. This has become a blocker for me.
Have a list of the added controls and use it when needed.
for (int i = 0; i < numberOfParameters; i++)
{
// ...
td2.Controls.Add(newLabel[i]);
td2.Controls.Add(genericControl);
td2.Controls.Add(txtBox[i]);
td2.Controls.Add(genericControl);
addedTextBoxes.Add(txtBox[i]);
// ...
}
And then from another part of your code:
var values = addedTextBoxes.Select(tb => tb.Text).ToList();
foreach (var txtBox in addedTextBoxes)
{
// ...
}
etc...
