I am trying to make a billing software and want to merge the rows with same barcode with a press of a button, and if that row contains remark then the row should not merge.
private void button3_Click(object sender, EventArgs e)
{
int GROW = dataGridView1.RowCount;
for(int i=0; i<GROW; i++)
{
DataGridViewRow row= dataGridView1.Rows[i];
string A = row.Cells[0].Value.ToString();
for(int j = 0; j< GROW; j++)
{
if(j == i)
{
}
else
{
DataGridViewRow rowb= dataGridView1.Rows[j];
string B = rowb.Cells[0].Value.ToString();
if (A == B)
{
string rema = row.Cells[8].Value.ToString();
string remb = rowb.Cells[8].Value.ToString();
if(rema == "" && remb == "")
{
string qa = row.Cells[2].Value.ToString();
string qb = rowb.Cells[2].Value.ToString();
decimal qad = Convert.ToDecimal(qa);
decimal qbd = Convert.ToDecimal(qb);
decimal tqd = qad + qbd;
string ra = row.Cells[7].Value.ToString();
string rb = rowb.Cells[7].Value.ToString();
decimal rad = Convert.ToDecimal(ra);
decimal rbd = Convert.ToDecimal(rb);
decimal trd = rad + rbd;
row.Cells[7].Value = trd;
row.Cells[2].Value= tqd;
dataGridView1.Rows.RemoveAt(j);
// i = i - 1;
GROW--;
}
}
}
}
}
Assuming your value is in Cell[2] and remark in Cell[8], something like this should work:
for (int i = 0; i < dataGridView1.Rows.Count; i++)
{
int k = 0;
for (int j = 0; j < dataGridView1.Rows.Count; j++)
{
// Check if values are same but remarks are different
if (dataGridView1.Rows[i].Cells[2].Value == dataGridView1.Rows[j].Cells[2].Value && dataGridView1.Rows[i].Cells[8].Value != dataGridView1.Rows[j].Cells[8].Value)
{
if (k != 0)
{
items.Rows.RemoveAt(j);
dataGridView1.DataSource = items;
}
k++;
}
}
}
NOTE: I have not tested this code but I hope you get the idea

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;

We can use below Answer
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--)

var result = Array.FindIndex(columnNames, element => element.EndsWith("QTY"));
var Arraymax = columnNames.Max();
int maxIndex = columnNames.ToList().IndexOf(Arraymax);
decimal MultiplicationResult = 0;
decimal currentCellResult = 0;
for (int j = 8; j < row.Cells.Count; j++)
{
var defaultvalue = row.Cells[j].Text.ToString();
var defaultvalueArray = defaultvalue.Split(' ');
var originalMultiplicationResult = defaultvalueArray.Count() == 2 ? defaultvalueArray.Last() : "0";
var originalCellValue = defaultvalueArray.Count() == 2 ? defaultvalueArray.First() : row.Cells[j].Text.ToString();

{
PGLQ = 0.ToString();
}
currentCellResult = Convert.ToDecimal(Quantity) * Convert.ToDecimal(GLQ);

I'm coding like below but it works incorrect.It perform(plus and delete) only 2->3 rows if data has 5->6 duplicate data.
Update and It works
for (int i = 0; i < dataGridView1.RowCount - 1; i++) //compare data
{
var Row = dataGridView1.Rows[i];
string abc = Row.Cells[1].Value.ToString() + Row.Cells[2].Value.ToString().ToUpper();
// MessageBox.Show(abc);
for (int j = i + 1; j < dataGridView1.RowCount; j++)
{
var Row2 = dataGridView1.Rows[j];
string def = Row2.Cells[1].Value.ToString() + Row2.Cells[2].Value.ToString().ToUpper();
if (abc == def)
{
Row.Cells[5].Value = Convert.ToDouble(Row.Cells[5].Value.ToString()) + Convert.ToDouble(Row2.Cells[5].Value.ToString());
dataGridView1.Rows.Remove(Row2);
j--;
}
}
}
This should do the trick for you:
for (int i = 0; i < dataGridView1.RowCount - 1; i++) //compare data
{
var Row = dataGridView1.Rows[i];
string abc = Row.Cells[0].Value.ToString() + Row.Cells[1].Value.ToString().ToUpper();
for (int j = i+1; j < dataGridView1.RowCount; j++)
{
var Row2 = dataGridView1.Rows[j];
string def = Row2.Cells[0].Value.ToString() + Row2.Cells[1].Value.ToString().ToUpper();
if (abc == def)
{
Row.Cells[2].Value = (int)Row.Cells[2].Value + (int)Row2.Cells[2].Value;
dataGridView1.Rows.Remove(Row2);
j--;
}
}
}
You basically need to keep track of j variable as you remove rows from the collection.
If you're a fan of LINQ and don't mind a bit of a convoluted code, here is another approach:
for (int i = 0; i < dataGridView1.RowCount; i++) //compare data
{
var R = dataGridView1.Rows[i];
var V = R.Cells[0].Value.ToString() + R.Cells[1].Value.ToString().ToUpper();
var DupRows = dataGridView1.Rows.Cast<DataGridViewRow>().Skip(i + 1).
Where(r => r.Cells[0].Value.ToString() + r.Cells[1].Value.ToString().ToUpper() == V);
R.Cells[2].Value = (int)R.Cells[2].Value + DupRows.Sum(r => (int)r.Cells[2].Value);
foreach (var DupRow in DupRows)
DupRow.Tag = "Del";
}
for (int i = 0; i < dataGridView1.RowCount; i++)
{
var R = dataGridView1.Rows[i];
if (R.Tag?.ToString() == "Del")
{
dataGridView1.Rows.Remove(R);
i--;
}
}
As a word of advice, this kind of stuff is handled far more easily in the back-end. Whatever your DataGridView is bound to, be it a DataTable or a generic collection, you should implement duplicate removal there instead of directly playing with DataGridView cells.
Is it possible to set two values in one for loop? I would like to create a string matrix [,], the first element (i) is variable, the second (j) is constant
int rowRun = 1;
string[,] costume = new string [elementsOfRunning, rowRun];
int columnRun = costume.GetLength(0);
for (int i = 0; i < columnRun; i++)
{
int rowOfRunning;
do
{
Console.WriteLine("Row of running (0-42)");
rowOfRunning = int.Parse(Console.ReadLine());
}
while (!(0 <= rowOfRunning && rowOfRunning <= 42));
string rowOfRunning2 = rowOfRunning.ToString();
}
And here I would like to set the i value for example: costume[i,j] = rowOfRunning; But I can't in this way.
for (int j = 0; j < rowRun; j++)
{
string comment = "";
do
{
Console.WriteLine("Write a comment: („verseny”, „terep”, „laza”, „fartlek”, „résztáv”");
comment = Console.ReadLine();
}
while (!comment.Contains(",") && comment != "verseny" && comment != "terep" && comment != "laza" && comment != "fartlek" && comment != "résztáv");
costume[i, j] = comment;
Console.WriteLine(costume[i,j]);
}
I'm not sure what you want to do but you can declare more than one variable in for loop like this:
var array = new Array[10, 10];
for (int i = 0, j = 1; i < 3; j++, i++)
{
Console.WriteLine("i:" + i + " j:" + j);
array[i,j] = Console.ReadLine();
}
I've found several examples that do this but with richTextBox instead. Is it even possible to replace words in a multi-line TextBox?
you can do this for searchin' the next word automatically in textbox
int t = 0;
private void FindNext(object sender, RoutedEventArgs e)
{
for (int i = t; i < NoteText.Text.Length-SearchBar.Text.Length; i++)
{
string x = "";
for (int j = 0; j < SearchBar.Text.Length; j++)
{
if(SearchBar.Text[j] == NoteText.Text[i+j])
{
x += NoteText.Text[i + j] + "";
}
else
{
x = "";
}
}
if(x == SearchBar.Text)
{
t = i+1;
NoteText.Focus();
NoteText.SelectAll();
NoteText.Select(i, SearchBar.Text.Length);
break;
}
if(i==NoteText.Text.Length - SearchBar.Text.Length - 1)
{
MessageBox.Show("The search was completed");
t = 0;
}
s = t;
}
}
I have a datagridview with many columns and many rows of data and i want to set some cells color to red or green,so that i have used below code
And as my code illustrates the column "exam" is not reading and not entering into the if condition.please suggest me what to do for my issue.
dataGridView2_RowPrePaint(object sender, DataGridViewRowPrePaintEventArgs e)//I have used this event
string unit = Convert.ToString(dataGridView2.Columns["exam"]);//One of my datagridview
//column name is exam and in that column cells will be unit1 or unit2 or unit3 or unit 4 or quarterly or halfyearly or yearly
if (unit == "Unit1" || unit == "Unit2" || unit == "Unit3" || unit == "Unit4")
{
for (int i = 0; i < dataGridView2.Rows.Count; i++)
{
for (int j = 7; j < dataGridView2.Rows[i].Cells.Count; j++)
{
if (Convert.ToInt32(dataGridView2.Rows[i].Cells[j].Value) < 13)
{
dataGridView2.Rows[i].Cells[j].Style.ForeColor = Color.Red;
}
else
{
dataGridView2.Rows[i].Cells[j].Style.ForeColor = Color.Green;
}
}
}
}
else
{
for (int i = 0; i < dataGridView2.Rows.Count; i++)
{
for (int j = 7; j < dataGridView2.Rows[i].Cells.Count; j++)
{
if (Convert.ToInt32(dataGridView2.Rows[i].Cells[j].Value) < 35 )
dataGridView2.Rows[i].Cells[j].Style.ForeColor = Color.Red;
else
dataGridView2.Rows[i].Cells[j].Style.ForeColor = Color.Green;
}
}
}
Instead of using == notation use .Equals() to check whether they are equal or not.
if (unit.Equals("Unit 1") ||unit.Equals("Unit1") || unit.Equals("Unit2") || unit.Equals("Unit3") || unit.Equals("Unit4"))
{
//your logic
}
apply the above logic and also use
string data = (string)MyDataGridView[Colnum, Rownum].Value;
Then you can simply loop rows and columns
Cheers! Hope it helps.
This is the code what i wanted exactly..
I hope it will help others..
