while creating pdf new page get first page data using itextsharp c#

I am trying to create a pdf in the attached format by using grouping using c#. The first page is fine but next page still first-page first column name exists. while creating a pdf new page get the first page data
I used
DeleteBodyRows()
for removing table rows but still the same :
foreach (DataRow row in dataTable.Rows)
{
//write in new row
var datatable = dataTable;
var departments = from r in datatable.Rows.OfType<DataRow>()
group r by r["emp_reader_id"] into g
select new { emp_reader_id = g.Key, Data = g };
foreach (var department in departments)
{
foreach (var roww in department.Data)
{

All new page contains the first page's first row continuously. Above is the code I tried.
Any help ?
Thanks!

add below line next to table.DeleteBodyRows()
To remove first row
table.DeleteRow(0);

Here I'm setting my formula with comma separated cell names eg:
SUM(A1,A2,A3.. etc)
The excel file is generating correctly. But the problem is the formula calculation is not happen when I open my excel file.
The formula works when I manually change a cell value in Column Type Agreed Flow.
And it can only identify values of manually edited cells.
How can I resolve this?

Formula recalculation is both an Excel and a workbook setting.
You could set it with at the workbook level with
workbook.CalcMode = ExcelCalcMode.Automatic;
If the user has set it to manual though, the formulas won't be recalculated.
If you want to ensure the saved values are correct you can force the calculation by calling
worksheet.Calculate();
You can also calculate the formulas at the workbook or range level, eg :
worksheet.Cells[j + 2, k + 1].Calculate();
or
package.Workbook.Calculate();
This is explained in the documentation. Keep in mind that EPPlus doesn't contain Excel's formula engine. It uses its own engine to parse and calculate formulas. Some things aren't supported

It worked when I change my formula as follows..
var addressList = new List<string>();
for (int i = 11; i <= k+1; i++)
{
addressList.Add(worksheet.Cells[((j + 2) -1) , i].Address);
}
var lstAdress = String.Join("+", addressList);
worksheet.Cells[j + 2, k + 1].Formula = "(" + lstAdress + ")";
I think there is an issue in my excel sheet when I use the SUM function So I write the formula without using it. Then it worked
(A1+B1+C1+D1+ ..... etc)

how to add alternative row formatting in EPP Plus C# .XLSX download

I am upgrading .xls download in .aspx page to .xlsx download using c# EppPlus. How can I add Alternative row background color like each other row has gray background ?
I am using the below code
public void DumpExcel(DataTable tbl)
{
using (ExcelPackage pck = new ExcelPackage())
{
//Create the worksheet
ExcelWorksheet ws = pck.Workbook.Worksheets.Add("Sheet1");
ws.Cells["A1"].LoadFromDataTable(tbl, true);
using (ExcelRange rng = ws.Cells["A1:AA1"])
{
rng.Style.Font.Bold = false;
rng.Style.Fill.PatternType = ExcelFillStyle.Solid; //Set Pattern for the background to Solid
rng.Style.Fill.BackgroundColor.SetColor(Color.FromArgb(0, 51, 153)); //Set color to dark blue
rng.Style.Font.Color.SetColor(Color.White);
rng.Style.Font.Size = 10;
}
// Add Word wrap
for (int i = 1; i <= tbl.Columns.Count; i++)
{
ws.Column(i).AutoFit();
ws.Column(i).Width = 20;
ws.Column(i).Style.WrapText = true;
ws.Column(i).Style.VerticalAlignment = ExcelVerticalAlignment.Top;
ws.Column(i).Style.Font.Size = 9;
}
//Write it back to the client
Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
Response.AddHeader("content-disposition", "attachment; filename=UserEntitleDLX.xlsx");
Response.BinaryWrite(pck.GetAsByteArray());
}
}

I think it should also be mentioned that there is an overload for LoadFromDataTable where you can pass a TableStyle like so
ws.Cells["A1"].LoadFromDataTable(tbl, true, TableStyles.Dark1);
If you want the tbl's area to be formatted from scratch then you could do something like this
for (var row = 1; row <= tbl.Rows.Count; row++)
{
for (var column = 1; column <= tbl.Columns; column++)
{
ws.Cells[row, column].Style.Font.Bold = false;
ws.Cells[row, column].Style.Fill.PatternType = ExcelFillStyle.Solid;
ws.Cells[row, column].Style.Font.Size = 10;
ws.Cells[row, column].Style.Fill.BackgroundColor.SetColor(column%2 == 0
? Color.Blue
: Color.Gray);
}
}

Below piece of code did the job for me
for (int row = ws.Dimension.Start.Row; row <= ws.Dimension.End.Row; row++)
{
int pos = row % 2;
ExcelRow rowRange = ws.Row(row);
ExcelFill RowFill = rowRange.Style.Fill;
RowFill.PatternType = ExcelFillStyle.Solid;
switch (pos)
{
case 0:
RowFill.BackgroundColor.SetColor(System.Drawing.Color.White);
break;
case 1:
RowFill.BackgroundColor.SetColor(System.Drawing.Color.LightGray);
break;
}
}

Here's a variation of the given answers I use (as extension). My requirements required a subset of columns be colored, not the whole row, and with more than just two colors.
public static void ApplyBackgroundColorsPerRow(
this ExcelWorksheet worksheet,
int startRow, int startColumn, int endRow, int endColumn,
List<System.Drawing.Color> colors)
{
if (startRow <= endRow)
{
int numberOfColors = colors.Count;
for (int row = startRow; row <= endRow; row++)
{
using (ExcelRange range = worksheet.Cells[row, startColumn, row, endColumn])
{
range.Style.Fill.PatternType = ExcelFillStyle.Solid;
range.Style.Fill.BackgroundColor.SetColor(colors[(row - startRow) % numberOfColors]);
}
}
}
}
Alternating white / gray (light gray is my recommendation over grey) would look like this:
worksheet.ApplyBackgroundColorsPerRow(
startRow: 1,
startColumn: 1,
endRow: 20,
endColumn: 5,
colors: new List<System.Drawing.Color>()
{
System.Drawing.Color.White,
System.Drawing.Color.LightGray
}
);

How can I change color of text in a cell of MS Excel?

I am using Microsoft.Office.Interop.Excel library.
I have a cell with values "Green Red". What I want is pretty simple. I want to insert "Green" text to be green and "Red" to be red, like that:
I am using this code to insert data in cell:
Excel.Application excelApp = new Excel.Application();
excelApp.Workbooks.Add();
// single worksheet
Excel._Worksheet workSheet = excelApp.ActiveSheet;
for (int startIndex = 0; startIndex < 10; startIndex++)
{
workSheet.Cells[1, (startIndex + 1)] ="Green" + " Red";
}
How to do it?
I've tried this approach, but I do not know what [RangeObject] is:
[RangeObject].Font.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);

Try:
workSheet.Cells[1, (i + 1)].Characters[start_pos, len].Font.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);
where start_pos and len is the part of the string where to apply color.
Your use case example:
Application excelApp = new Application();
excelApp.Workbooks.Add();
// single worksheet
_Worksheet workSheet = excelApp.ActiveSheet;
string Green = "Green";
string Red = "Red";
for (int start = 0; start < 10; start++)
{
Range ColorMeMine = workSheet.Cells[1, (start + 1)];
ColorMeMine.Value = string.Format("{0} {1}", Green, Red);
ColorMeMine.Characters[0, Green.Length].Font.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Green);
ColorMeMine.Characters[Green.Length + 1, Green.Length + 1 + Red.Length].Font.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);
}

How to set the position of an Excel chart with cell value from C#?

I'm using following method to create and position the excel chart beside table data. below code is working fine, but chart position(height) is creating problem when number of charts increase.
There is any solution for draw chart with cell value? or other thing that may be used by me to keep chart beside table data.
I want to print result of following method page by page and therefore want to place it correctly.
below is my code:
Excel.Application xla = new Excel.Application();

if (CheckBox1.Checked == true)
{
string table_name, chart_name;
table_name = "Ration Table";
chart_name = "Ratio";
string st = "";
con.Open();
trying(ws, st, height, uppercell, cell, table_name, chart_name);
con.Close();
cell = cell + 33;
uppercell = "B" + cell;
height = 496 + 75;//height + 300;
}
public void trying(Excel.Worksheet ws,string st,double height,string uppercell,int cell,string table_name,string chart_name)
