[英]How do I export 2 gridviews into 2 separate sheets in one MS Excel file?
如何通过单击1按钮将2个gridviews(GridView1和GridView2)导出到一个MS Excel文件中的2个单独的工作表中? 目前,我只能将1个gridview导出到Excel工作表,该工作表的文件名与工作表名称相同。 但是我想将gridviews分为2个单独的工作表,我希望工作表名称由我自己定义/设置。 谢谢
public void ExportGridToExcel()
{
Response.Clear();
Response.Buffer = true;
Response.ClearContent();
Response.ClearHeaders();
Response.Charset = "";
string FileName ="Export"+DateTime.Now+".xls";
StringWriter strwritter = new StringWriter();
HtmlTextWriter htmltextwrtter = new HtmlTextWriter(strwritter);
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.ContentType = "application/vnd.ms-excel";
Response.AddHeader("Content-Disposition","attachment;filename=" + FileName);
GridView1.GridLines = GridLines.Both;
GridView1.HeaderStyle.Font.Bold = true;
GridView1.RenderControl(htmltextwrtter);
Response.Write(strwritter.ToString());
Response.End();
}
//编辑我的答案,因为只有一个导出按钮:看一下这个问题 :
首先添加以下名称空间:
using Excel = Microsoft.Office.Interop.Excel;
using System.Reflection;
using System.IO;
因此,基本上,您应该拥有(或继续制作)2个DataTable(以绑定到2个gridviews):dt1和dt2
制作数据集并向其中添加2个数据表
DataSet dataset = new DataSet();
dataset.Tables.Add(dt1);
dataset.Tables.Add(dt2);
然后
//Print using Ofice InterOp
Excel.Application excel = new Excel.Application();
var workbook = (Excel._Workbook)(excel.Workbooks.Add(Missing.Value));
for (var i = 0; i < dataset.Tables.Count; i++)
{
if (workbook.Sheets.Count <= i)
{
workbook.Sheets.Add(Type.Missing, Type.Missing, Type.Missing,
Type.Missing);
}
//NOTE: Excel numbering goes from 1 to n
var currentSheet = (Excel._Worksheet)workbook.Sheets[i + 1];
for (var y = 0; y < dataset.Tables[i].Rows.Count; y++)
{
for (var x = 0; x < dataset.Tables[i].Rows[y].ItemArray.Count(); x++)
{
currentSheet.Cells[y+1, x+1] = dataset.Tables[i].Rows[y].ItemArray[x];
}
}
}
string outfile = @"C:\APP_OUTPUT\EXCEL_TEST.xlsx";
workbook.SaveAs( outfile, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Excel.XlSaveAsAccessMode.xlNoChange,
Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing);
workbook.Close();
excel.Quit();
更改工作表名称,我相信您可以这样做:
currentSheet.Name = "your sheet name"
您需要修改代码,以便在excel文件中创建工作表,然后将数据从网格手动复制到excel文件,并将此代码创建为以Grid,Sheetname和Sheetid之类的参数(如1,2等)作为参数的函数然后在按钮单击事件中,分别对grid1调用两次,对grid2调用一次,分别使用不同的工作表名称和工作表ID 1和2对其进行调用。 该函数的代码如下。
在按钮单击事件中编写这两行代码,然后通过将excel应用程序和工作簿也作为参数传递给每个网格两次调用该函数。
// 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);
public void ExportToExcel(Microsoft.Office.Interop.Excel._Application app, Microsoft.Office.Interop.Excel._Workbook workbook,GridView gridview,string SheetName,int sheetid)
{
// 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["Sheet"+ sheetid];
worksheet = workbook.ActiveSheet;
// changing the name of active sheet
worksheet.Name = sheetname;
// storing header part in Excel
for(int i=1;i<gridview.Columns.Count+1;i++)
{
worksheet.Cells[1, i] = gridview.Columns[i-1].HeaderText;
}
// storing Each row and column value to excel sheet
for (int i=0; i < gridview.Rows.Count-1 ; i++)
{
for(int j=0;j<gridview.Columns.Count;j++)
{
worksheet.Cells[i + 2, j + 1] = gridview.Rows[i].Cells[j].Value.ToString();
}
}
// save the application
workbook.SaveAs("c:\\output.xls",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();
}
