I have sample code block and you can see below and this code working effectively. But this code not enough for me. So i need improve my code.
Firstly, i have datagridview and this datagridview creating my datablock but i could not write new row to under before row. When i add new data block to datagridvew then new data has must write under older data on excel file.
private void buttonExcel_Click(object sender, EventArgs e)
{
// creating Excel Application
Microsoft.Office.Interop.Excel._Application app = new Microsoft.Office.Interop.Excel.Application();
// creating new WorkBook within Excel application
Microsoft.Office.Interop.Excel._Workbook workbook = app.Workbooks.Add(Type.Missing);
// creating new Excelsheet in workbook
Microsoft.Office.Interop.Excel._Worksheet worksheet = null;
// see the excel sheet behind the program
app.Visible = true;
// get the reference of first sheet. By default its name is Sheet1.
// store its reference to worksheet
worksheet = workbook.Sheets["Sheet1"];
worksheet = workbook.ActiveSheet;
// changing the name of active sheet
worksheet.Name = "Exported from gridview";
// storing header part in Excel
for (int i = 1; i < dataGridView1.Columns.Count + 1; i++)
{
worksheet.Cells[1, i] = dataGridView1.Columns[i - 1].HeaderText;
}
// storing Each row and column value to excel sheet
for (int i = 0; i < dataGridView1.Rows.Count - 1; i++)
{
for (int j = 0; j < dataGridView1.Columns.Count; j++)
{
worksheet.Cells[i + 2, j + 1] = dataGridView1.Rows[i].Cells[j].Value.ToString();
}
}
// save the application
workbook.SaveAs("c:\\PROJE TEKLİF FİYAT.xlsx", Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
// Exit from the application
app.Quit();
}
I'd used the ClosedXML Library (via NuGet) for this as it makes saving a datatable to excel pretty simple.
First, import your existing spreadsheet as a datatable like so:
public DataTable GetData(string filename)
{
using (XLWorkbook workBook = new XLWorkbook(filename))
{
//Read the first Sheet from Excel file.
IXLWorksheet workSheet = workBook.Worksheet(1);
//Create a new DataTable.
DataTable dt = new DataTable();
//Loop through the Worksheet rows.
bool firstRow = true;
foreach (IXLRow row in workSheet.Rows())
{
//Use the first row to add columns to DataTable.
if (firstRow)
{
foreach (IXLCell cell in row.Cells())
{
dt.Columns.Add(cell.Value.ToString());
}
firstRow = false;
}
else
{
//Add rows to DataTable.
dt.Rows.Add();
int i = 0;
foreach (IXLCell cell in row.Cells(row.FirstCellUsed().Address.ColumnNumber, row.LastCellUsed().Address.ColumnNumber))
{
dt.Rows[dt.Rows.Count - 1][i] = cell.Value.ToString();
i++;
}
}
}
return dt;
}
}
Then convert datagridview to datatable, then merge the existing data w/ the datagridview data into one datatable, then save as XLSX.
using ClosedXML.Excel;
...
private void saveDGV(DataTable existing)
{
//Creating DataTable.
DataTable dt = new DataTable();
//Adding the Columns.
foreach (DataGridViewColumn column in dataGridView1.Columns)
{
dt.Columns.Add(column.HeaderText, column.ValueType);
}
//Adding the Rows.
foreach (DataGridViewRow row in dataGridView1.Rows)
{
dt.Rows.Add();
foreach (DataGridViewCell cell in row.Cells)
{
dt.Rows[dt.Rows.Count - 1][cell.ColumnIndex] = cell.Value.ToString();
}
}
existing.Merge(dt);
using (XLWorkbook wb = new XLWorkbook())
{
wb.Worksheets.Add(existing, "Exported from gridview");
//Adjust widths of Columns.
wb.Worksheet(1).Columns().AdjustToContents();
wb.SaveAs("c:\\PROJE TEKLİF FİYAT.xlsx")
}
}
You would use this like so:
using ClosedXML.Excel;
...
private void buttonExcel_Click(object sender, EventArgs e)
{
DataTable existing = GetData("c:\\PROJE TEKLİF FİYAT.xlsx");
saveDGV(existing);
}

I'm generating an excel file in C# and excel file is format is as follows.
And Columns From C1 will be dynamic since there can be several dates.
And what I need to do is only allow editing for rows with Ctype
YYY
Is there any way to identify rows with Ctype = YYY
The code I use to generate excel is as follows
public string ExcelGenerator()
{
DataTable dt = GetDataTable();
var fileName = "ExcelFile";
var excelApp = new Application();
var workbooks = excelApp.Workbooks;
var excelWorkBook = workbooks.Add(XlWBATemplate.xlWBATWorksheet);
var sheets = excelWorkBook.Sheets;
var excelWorkSheet = sheets[1];
excelWorkSheet.Name = "ExcelFile";
int iCol = 1;
// Add column headings...
foreach (DataColumn c in dt.Columns)
{
excelWorkSheet.Cells[1, iCol] = c.ColumnName; ;
((Range)excelWorkSheet.Cells[1, iCol]).Interior.Color = ColorTranslator.ToOle(Color.DarkGray);
iCol++;
}
// for each row of data...
for (int j = 0; j < dt.Rows.Count; j++)
{
for (int k = 0; k < dt.Columns.Count; k++)
{
excelWorkSheet.Cells[j + 2, k + 1] = dt.Rows[j].ItemArray[k].ToString();
}
}
string fullpath = Path.Combine(excelPath, fileName);
if (File.Exists(fullpath))
{
try
{
File.Delete(fullpath);
}
catch (IOException e)
{
Console.Write(e.Message);
}
}
excelApp.DisplayAlerts = false;
excelWorkBook.SaveAs(fullpath, Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookDefault, Type.Missing, Type.Missing, true, false, XlSaveAsAccessMode.xlNoChange, XlSaveConflictResolution.xlLocalSessionChanges, Type.Missing, Type.Missing);
excelWorkBook.Close(false, Type.Missing, Type.Missing);
excelApp.Quit();
Marshal.ReleaseComObject(workbooks);
Marshal.ReleaseComObject(excelWorkSheet);
Marshal.ReleaseComObject(sheets);
Marshal.ReleaseComObject(excelWorkBook);
Marshal.ReleaseComObject(excelApp);
excelWorkSheet = null;
excelWorkBook = null;
excelApp = null;
workbooks = null;
GC.WaitForPendingFinalizers();
GC.Collect();
return fileName;
}
Excel.Office.Interop don't allow range unprotection by programmatically.
For more information, you may visit this website.
https://msdn.microsoft.com/en-us/library/dkcs53f3.aspx
But if you use EPPlus library, you can do like Excel users.
if you allow selective editable column, excel requires sheet protection = true and some unprotected range.
(using EPPlus)
excelWorkSheet.Protection.IsProtected = true;
excelWorkSheet.ProtectedRanges.Add("editable", new ExcelAddress("B"));
hi i exported gridview data into excel but unfortunately the data inside the exported file was different,supposed to be a datatable.
Below is my script in export button, can you tell me what is wrong in my script. I am new in ASP.net thanks
try
{
Microsoft.Office.Interop.Excel.Application excel = new Microsoft.Office.Interop.Excel.Application();
excel.Visible = true;
Microsoft.Office.Interop.Excel.Workbook workbook = excel.Workbooks.Add(System.Reflection.Missing.Value);
Microsoft.Office.Interop.Excel.Worksheet sheet1 = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Sheets[1];
int StartCol = 1;
int StartRow = 1;
int j = 0, i = 0;
//Write Headers
for (j = 0; j < GridView1.Columns.Count; j++)
{
Microsoft.Office.Interop.Excel.Range myRange = (Microsoft.Office.Interop.Excel.Range)sheet1.Cells[StartRow, StartCol + j];
myRange.Value = GridView1.Columns[j].HeaderText;
}
StartRow++;
//Write datagridview content
for (i = 0; i < GridView1.Rows.Count; i++)
{
for (j = 0; j < GridView1.Columns.Count; j++)
{
try
{
Microsoft.Office.Interop.Excel.Range myRange = (Microsoft.Office.Interop.Excel.Range)sheet1.Cells[StartRow + i, StartCol + j];
myRange.Value2 = GridView1.Rows[i].Cells[j].Text + ";" == null ? "" : GridView1.Rows[i].Cells[j].Text + ";";
}
catch
{
GridView1.DataBind();
}
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
// ScriptManager.RegisterClientScriptBlock(this, this.GetType(),
// "alertMessage",
// "alert(ex.ToString());", true);
}
You can export datagridview data to an excel using the below method:
public void ExportToExcel(DataGridView dgv)
{
try
{
dgv.SelectAll();
dgv.ClipboardCopyMode = DataGridViewClipboardCopyMode.EnableAlwaysIncludeHeaderText;
DataObject doj = dgv.GetClipboardContent();
Clipboard.SetDataObject(doj);
dgv.ClearSelection();
Microsoft.Office.Interop.Excel.Application exap = new Microsoft.Office.Interop.Excel.Application();
exap.Visible = true;
Workbook exwb = (Workbook)exap.Workbooks.Add();
Worksheet exws = (Worksheet)exwb.Sheets["Sheet1"];
exws.Paste();
Clipboard.Clear();
Range cell1 = exws.Cells[1, 2];
Range cell2 = exws.Cells[dgv.Rows.Count + 1, dgv.ColumnCount + 1];
Range cell3 = exws.Cells[1, dgv.ColumnCount + 1];
Range range = exws.get_Range(cell1, cell2);
Range colorrange = exws.get_Range(cell1, cell3);
range.Borders.Weight = XlBorderWeight.xlThin;
colorrange.Interior.Color = System.Drawing.Color.SteelBlue;
colorrange.Font.Color = System.Drawing.Color.White;
SaveFileDialog sfd = new SaveFileDialog();
sfd.Filter = "Excel File 2010 (*.xlsx)|*.xlsx|Excel File 2003 (*.xls)|*.xls";
if (sfd.ShowDialog() == DialogResult.OK)
{
exwb.SaveAs(sfd.FileName, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, XlSaveAsAccessMode.xlNoChange, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
}
}
catch(System.Exception ex)
{
MessageBox.Show(ex.Message);
}
}
This method copies all data in the datagridview & pastes it in an excel.You ofcourse need to add a reference to Microsoft.Office.Interop.Excel.
Alternately if you wish to export a datatable to excel you can try below method:
public void ExporttoExcel(System.Data.DataTable dtbl)
{
StringBuilder Output = new StringBuilder();
//The first "line" will be the Headers.
for (int i = 0; i < dtbl.Columns.Count; i++)
{
Output.Append(dtbl.Columns[i].ColumnName + "\t");
}
Output.Append("\n");
//Generate Cell Value Data
foreach (DataRow Row in dtbl.Rows)
{
if (Row.RowState != DataRowState.Deleted)
{
for (int i = 0; i < Row.ItemArray.Length; i++)
{
//Handling the last cell of the line.
if (i == (Row.ItemArray.Length - 1))
{
Output.Append(Row.ItemArray[i].ToString() + "\n");
}
else
{
Output.Append(Row.ItemArray[i].ToString() + "\t");
}
}
}
}
Clipboard.SetText(Output.ToString());
Microsoft.Office.Interop.Excel.Application exap = new Microsoft.Office.Interop.Excel.Application();
exap.Visible = true;
Workbook exwb = (Workbook)exap.Workbooks.Add();
Worksheet exws = (Worksheet)exwb.Sheets["Sheet1"];
exws.Paste();
Clipboard.Clear();
Range cell1 = exws.Cells[1, 1];
Range cell2 = exws.Cells[dtbl.Rows.Count, dtbl.Columns.Count];
Range cell3 = exws.Cells[1, dtbl.Columns.Count];
Range range = exws.get_Range(cell1, cell2);
Range colorrange = exws.get_Range(cell1, cell3);
range.Borders.Weight = XlBorderWeight.xlThin;
colorrange.Interior.Color = System.Drawing.Color.SteelBlue;
colorrange.Font.Color = System.Drawing.Color.White;
SaveFileDialog sfd = new SaveFileDialog();
sfd.Filter = "Excel File 2010 (*.xlsx)|*.xlsx|Excel File 2003 (*.xls)|*.xls";
if (sfd.ShowDialog() == DialogResult.OK)
{
exwb.SaveAs(sfd.FileName, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, XlSaveAsAccessMode.xlNoChange, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
}
}
Please check if these methods help.
use Text.Replace(" ", "")
myRange.Value2 = GridView1.Rows[i].Cells[j].Text.Replace(" ", "") + ";" == null ? "" : GridView1.Rows[i].Cells[j].Text + ";";
in markup
<asp:BoundField DataField="EmployeeName" HeaderText="Name" NullDisplayText=" "/>
I suspect your GridView Bind fails. Below is the method which you can try.
private void ExportToExcel()
{
//First fetch all records from grid to dataset
DataSet dset = new DataSet();
dset.Tables.Add();
//First Add Columns from gridview to excel
for (int i = 0; i < gridView.Columns.Count; i++) //GridView is id of gridview
{
dset.Tables[0].Columns.Add(gridView.Columns[i].HeaderText);
}
//add rows to the table
System.Data.DataRow dr1;
for (int i = 0; i < gridView.Rows.Count; i++)
{
dr1 = dset.Tables[0].NewRow(); //For Example There are only 3 columns into gridview
System.Web.UI.WebControls.Label lblCCName =
(System.Web.UI.WebControls.Label)gridView.Rows[i].Cells[0].FindControl("lblCCName");
System.Web.UI.WebControls.Label lblItemName =
(System.Web.UI.WebControls.Label)gridView.Rows[i].Cells[0].FindControl("lblItemName");
System.Web.UI.WebControls.Label lblItemCode =
(System.Web.UI.WebControls.Label)gridView.Rows[i].Cells[0].FindControl("lblItemCode");
dr1[0] = lblCCName.Text.ToString();
dr1[1] = lblItemName.Text.ToString();
dr1[2] = lblItemCode.Text.ToString();
dset.Tables[0].Rows.Add(dr1);
}
//below code is export dset to excel
ApplicationClass excel = new ApplicationClass();
Workbook wBook;
Worksheet wSheet;
wBook = excel.Workbooks.Add(System.Reflection.Missing.Value);
wSheet = (Worksheet)wBook.ActiveSheet;
System.Data.DataTable dt = dset.Tables[0];
System.Data.DataColumn dc = new DataColumn();
int colIndex = 0;
int rowIndex = 4;
foreach (DataColumn dcol in dt.Columns)
{
colIndex = colIndex + 1;
excel.Cells[5, colIndex] = dcol.ColumnName;
}
foreach (DataRow drow in dt.Rows)
{
rowIndex = rowIndex + 1;
colIndex = 0;
foreach (DataColumn dcol in dt.Columns)
{
colIndex = colIndex + 1;
excel.Cells[rowIndex + 1, colIndex] = drow[dcol.ColumnName];
}
}
wSheet.Columns.AutoFit();
// Server File Path Where you want to save excel file.
String strFileName = Server.MapPath("~\\Images\\StockStatement.xls");
Boolean blnFileOpen = false;
try
{
System.IO.FileStream fileTemp = File.OpenWrite(strFileName);
fileTemp.Close();
}
catch
{
blnFileOpen = false;
}
if (System.IO.File.Exists(strFileName))
//It checks if file exists then it delete that file.
{
System.IO.File.Delete(strFileName);
}
}
In the Button_Click() event, call this function.
Hi this is were i came up after long journey, i used the Aspose method on Exporting Gridview in Excel, it's simple yet so powerfull! hope this will help,
Code behind Export_button:
//Instantiate a new workbook
Aspose.Cells.Workbook workbook = new Aspose.Cells.Workbook();
//Get the first worksheet in the workbook
Aspose.Cells.Worksheet worksheet = workbook.Worksheets[0];
//Import data from GridView control to fill the worksheet
worksheet.Cells.ImportGridView(GridView1, 0, 0, new Aspose.Cells.ImportTableOptions() { IsFieldNameShown = true });
worksheet.AutoFitColumns();
//Send result to client in XLS format
workbook.Save(this.Response, "export.xls", ContentDisposition.Attachment, new Aspose.Cells.XlsSaveOptions());
I want to make changes to an existing file named "Original" in the directory "C:\Users\Twiga\Documents\VisualStudio2010\Projects\MarkSheetSystem\Original.xls".
Currently, I am only able to save the data that I have exported from my datagridview1 to a new file but that is not my intention.
Below is the code:
private void btnexcel_Click(object sender, EventArgs e)
{
Microsoft.Office.Interop.Excel._Application excel = new Microsoft.Office.Interop.Excel.Application();
Microsoft.Office.Interop.Excel._Workbook workbook = excel.Workbooks.Add(Type.Missing);
Microsoft.Office.Interop.Excel._Worksheet worksheet = null;
try
{
worksheet = workbook.ActiveSheet;
worksheet.Name = "Marksheet 1";
worksheet.Cells[12, 1] = dataGridView1.Rows[0].Cells[0].Value.ToString();
int cellRowIndex = 10;
int cellColumnIndex = 1;
//Loop through each row and read value from each column.
for (int i = 0; i < dataGridView1.Rows.Count; i++)
{
for (int j = 1; j < dataGridView1.Columns.Count - 1; j++)
{
// Excel index starts from 1,1. As first Row would have the Column headers, adding a condition check.
if (cellRowIndex == 0)
{
worksheet.Cells[cellRowIndex, cellColumnIndex] = dataGridView1.Columns[j].HeaderText;
}
else
{
worksheet.Cells[cellRowIndex, cellColumnIndex] = dataGridView1.Rows[i].Cells[j].Value.ToString();
}
cellColumnIndex++;
}
cellColumnIndex = 1;
cellRowIndex++;
}
//Getting the location and file name of the excel to save from user.
SaveFileDialog saveDialog = new SaveFileDialog();
saveDialog.Filter = "Excel files (*.xlsx)|*.xlsx|All files (*.*)|*.*";
saveDialog.FilterIndex = 2;
if (saveDialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
workbook.SaveAs(saveDialog.FileName);
MessageBox.Show("The marksheet has been saved successfully!");
}
}
catch (System.Exception ex)
{
MessageBox.Show(ex.Message);
}
finally
{
excel.Quit();
workbook = null;
excel = null;
}
}
Pertinent to your task, it would be better to export data to Excel Workbook from the DataGridView underlying DataTable (e.g. DataTable _dt = (DataTable)(datagridview1.DataSource)) as shown in the following C# sample code snippet:
/// <summary>
/// export DataTable to Excel (C#)
/// </summary>
internal static void Export2Excel(DataTable dataTable)
{
object misValue = System.Reflection.Missing.Value;
Microsoft.Office.Interop.Excel.Application _appExcel = null;
Microsoft.Office.Interop.Excel.Workbook _excelWorkbook = null;
Microsoft.Office.Interop.Excel.Worksheet _excelWorksheet = null;
try
{
// excel app object
_appExcel = new Microsoft.Office.Interop.Excel.Application();
// excel workbook object added
// can be replaced with _appExcel.Workbooks.Open(...)
_excelWorkbook = _appExcel.Workbooks.Add(misValue);
_excelWorksheet = _appExcel.ActiveWorkbook.ActiveSheet as Microsoft.Office.Interop.Excel.Worksheet;
// column names row (range obj)
Microsoft.Office.Interop.Excel.Range _columnsNameRange;
_columnsNameRange = _excelWorksheet.get_Range("A1", misValue).get_Resize(1, dataTable.Columns.Count);
// column names array to be assigned to _columnNameRange
string[] _arrColumnNames = new string[dataTable.Columns.Count];
for (int i = 0; i < dataTable.Columns.Count; i++)
{
// array of column names
_arrColumnNames[i] = dataTable.Columns[i].ColumnName;
}
// assign array to column headers range, make 'em bold
_columnsNameRange.set_Value(misValue, _arrColumnNames);
_columnsNameRange.Font.Bold = true;
// populate data content row by row
for (int Idx = 0; Idx < dataTable.Rows.Count; Idx++)
{
_excelWorksheet.Range["A2"].Offset[Idx].Resize[1, dataTable.Columns.Count].Value =
dataTable.Rows[Idx].ItemArray;
}
// Autofit all Columns in the range
_columnsNameRange.Columns.EntireColumn.AutoFit();
}
catch { throw; }
}
This will significantly improve the performance by exporting the entire data row at once instead of doing it cell-by-cell.
The only changes you have to make is to replace the line that adds new Workbook:
_excelWorkbook = _appExcel.Workbooks.Add(misValue);
with another one, opening the existing Excel File (e.g. "ExcelFilePath"), like:
_excelWorkbook = _appExcel.Workbooks.Open("ExcelFilePath",
Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing);
Hope this may help.
I am using below code to export excel using Microsoft.Office.Interop.Excel. [Ms office 2003].

IS Get_Range() has some limitation for rows/Columns?
As I know for MS Office 2003 column's limit is 256, not sure about rows limt.
Thanks
Excel 2003 can have a maximum of 65536 rows in a single worksheet (specification)
Excel 2007 and newer can have 1048576 rows (specification: Excel 2007, Excel 2010 and Excel 2013)
Excel 2003 row limit is 65,536 - http://support.microsoft.com/kb/120596
I could export data of datagridview to excel. But the actual format of datagridview was not exported i.e., font, color and space. So, is there any best way to export datagridview to excel i.e. not only data but also the look.
The sample look is this:
Try CSV export
private void ToCsV(DataGridView dGV, string filename)
{
string separator = ",";
StringBuilder stOutput = new StringBuilder();
// Export titles:
StringBuilder sHeaders = new StringBuilder();
for (int j = 0; j < dGV.Columns.Count; j++)
{
sHeaders.Append(dGV.Columns[j].HeaderText);
sHeaders.Append(separator);
}
stOutput.AppendLine(sHeaders.ToString());
// Export data.
for (int i = 0; i < dGV.RowCount - 1; i++)
{
StringBuilder stLine = new StringBuilder();
for (int j = 0; j < dGV.ColumnCount; j++)
{
stLine.Append(Convert.ToString(dGV[j, i].Value));
stLine.Append(separator);
}
stOutput.AppendLine(stLine.ToString());
}
File.WriteAllText(filename, stOutput.ToString());
}
Before you write code in button_Click event, you must add a reference to the Microsoft.Office.Interop.Excel object library.
Right click on your project and select Add Reference menu. After that go to .NET tab and select and add Microsoft.Office.Interop.Excel.
Write the below code in button_Click event.
// button_Click event
private void button11_Click(object sender, EventArgs e)
{
// creating Excel Application
string fileName = String.Empty;
Microsoft.Office.Interop.Excel._Application app = new Microsoft.Office.Interop.Excel.Application();
// creating new WorkBook within Excel application
Microsoft.Office.Interop.Excel._Workbook workbook = app.Workbooks.Add(Type.Missing);
// creating new Excelsheet in workbook
Microsoft.Office.Interop.Excel._Worksheet worksheet = null;
// see the excel sheet behind the program
app.Visible = true;
// get the reference of first sheet. By default its name is Sheet1.
// store its reference to worksheet
try
{
//Fixed:(Microsoft.Office.Interop.Excel.Worksheet)
worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Sheets["Sheet1"];
worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.ActiveSheet;
// changing the name of active sheet
worksheet.Name = "Exported from AMIT";
// storing header part in Excel
for (int i = 1; i < dataGridView1.Columns.Count + 1; i++)
{
worksheet.Cells[1, i] = dataGridView1.Columns[i - 1].HeaderText;
}
// storing Each row and column value to excel sheet
for (int i = 0; i < dataGridView1.Rows.Count - 1; i++)
