I am binding data from a dataset to a grid and exporting data from the grid to an excel.if the the number of items in the grid is greater than 50000,an error message is displayed.
So i want to split the data and display it in different worksheets in excel.(Am working in a web application)
using this code for exporting to excel
gvExcel.DataSource = DTS; gvExcel.DataBind(); Response.AddHeader("content-disposition", "attachment; filename= filename.xls"); Response.ContentType = "application/excel"; StringWriter sw = new StringWriter(); HtmlTextWriter htw = new HtmlTextWriter(sw); gvExcel.RenderControl(htw); // Style is added dynamically Response.Write(style); Response.Write(sw.ToString()); Response.End();
is there any way that i could export multiple tables already formatted into multiple excel sheets. I know how to export data to multiple sheets through dataset while looping through tables, rows and columns and then add styles.
But I really want to export formatted html tables each into seperate sheet
I was in need of exporting multiple tables in a DataSet to an Excel file with multiple sheets. I found a very good article in [URL].[URL] was able to successfully export each of my datatables in the dataset to excel worksheets. This solution worked for small number of rows. But when the data got larger I am consistently getting the system.outofmemoryexception. THis is because the code is using up the memory when creating excel.
I have multiple gridviews to be exported to excel. 1 gridview per worksheet.
How to do that ? ( or in general how to write an html string to a worksheet )
This is to be done in asp.net , server side.
I can create multiple worksheets via epplus.codeplex.com nicely, but it works on cell level. I could export DataTable, but how to export Gridview's HTML ?
In C# ASP.NET 3.5 web application, I need to export multiple datatables (or a dataset) to an Excel 2007 file with multiple sheets, and then provide the user with 'Open/Save' dialog box, WITHOUT saving the Excel file on the web server.
I have used Excel Interop before. I have been reading that it's not efficient and is not the best approach to achieve this and there are more ways to do it, 2 of them being: 1) Converting data in datatables to an XML string that Excel understands 2) Using OPEN XML SDK 2.0.
It looks like OPEN XML SDK 2.0 is better, please let me know. Are there any other ways to do it? I don't want to use any third-party tools.
If I use OPEN XML SDK, it creates an excel file, right? I don't want to save it on the (Windows 2003) server hard drive (I don't want to use Server.MapPath, these Excel files are dynamically created, and they are not required on the server, once client gets them). I directly want to prompt the user to open/save it. I know how to do it when the 'XML string' approach is used.
I have an excel sheet with 2 tabs and has data in those 2 sheets(sheet1, sheet2) which correspond to different tables in the same database. This excel sheet gets updated daily, I am wiriting a console app( which will later be a batch build). I have to insert the data from the excel sheet to corresponding tables (table1, table2,table3) in database when i run it and and also if the table has the same data already present it should ignore and if there are any modifications done the data it should update the table. I know we can do this using ado.net or LINQ, I am a little new to database based programming .
The file you are trying to open is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?
When yes is clicked it opens in excel but in some other format I think for I cannot AUTOSUM or sum the values result always as zero for numbers appears as text as " 222" . even if i try to format cells with numbers it does not works.
This is an ASP.NET web app built using VS2008. I created a standalone class with a method that exports the entire page, text fields, gridviews, images, everything to an Excel worksheet. It works fine. When I dropped the same class in another web app and tried to call it from a page, I get this error message:
I need the code for exporting aspx report page(static content without any html component but contains css style) to excel page without using any asp.net component like datagrid or any other.Please send me the complete code.
I need to export data to multiple worksheets based on some conditions. Currently i am able to export the data to a single sheet in excel using below code,
I've got an .rdlc report which I print from my .net app (C# Visual Studio 2005), where I use a RemoteReportPrinter object. I give it as parameters the server name, report name, report parameters, etc. Works fine. My question is, I would live to do an analagous export of that report to Excel. Set it up exactly the same, but have it export to Excel rather than print, probably using some other type of object than RemoteReportPrinter.
I'm exporting a Gridview to excel. I get all the gridview header and content in excel in addition to that i need to add a header text like report name in header of the excel sheet with line break in header.
I tried the solution in this link [URL] by adding
Table.Caption = "Header Text" Table.CaptionAlign = TableCaptionAlign.Top but i get error Reference to a non shared member requires an object reference.
Now the same code when I copy it in my project having masterpage . there is no compiler error but it is genereating excel file withno data in it but in fact there is data in the grid view at runtime.
I have a project in vb with a gridview in a multiview and i want to save in a workbook excel the gridview displayed data. I have read many articles but in the end i have downloaded the code from URL...and i adapted for my code. The problem is that when i press the ExporttoExcel button it's exporting only this...I cannot figure out that is the problem.
I've created a function that takes a datatable and exports it to excel by creating a Table.
When the file exported excel says "this file is in a different format than it's extension, do you wnat to open it anyway?". I'd like to get rid of this message if I can. and...There is an extra row at the top of the the excel file (row 0) and it's empty.
trying to export a dataset to excel directly. I'm repeating, it's a dataset to excel (NOT DATA GRID OR GRID VIEW TO EXCEL). The problem I face is formatting. I'm exporting the excel which has aroung 13 columns.
A column should be in dd/MM/yyyy 00:00:00 format. Time will always be 00:00:00. It is exporting in correct format only, but for example when the date is Jan 05, 2010, when it comes from database it shows correct format as05/01/2010 00:00:00. When it binds, it binds as 5/1/2010 00:00 which is not suppose to happen.
