I have a report which is created using a .rdlc. And populated using a List object. The report when exported to excel has a problem. The numeric colums show up as text and the tooltip in excel says "The number in this cell is formatted as text or preceded by an apostrophe". How can I get the number to show up as numeric?
View 1 RepliesI have a simple export to excel functionality in my application. Code is :

when I used a code of exporting gridview into excel this code worked for a new website which is without masterpage.
my code:
public override void VerifyRenderingInServerForm(Control control) { }
protected void BtnGenerateReport_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition",
"attachment;filename=GridViewExport.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();.....
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'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.
View 1 RepliesI'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.
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.

<style> .textmode { mso-number-format:@; } </style><div>

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
On two of my web forms I have the ability to export a gridview to an excel file. On my local machine. it works. So when I click an image button it gives me the option of opening or saving a gridview as Excel.
However, when I run on the web server. It does not give me the option to open or save, it just opens the gridview as an excel document when the button is clicked.
Even stranger: I have this running on two separate forms. On one form when it opens the gridview as an Excel file it includes a tool bar, so that If a user wishes they could do a 'file', 'save'; However the other one does not have a tool bar?
Ideally I would like them to get the prompt like on the local machine, to open or save.
I am having nearly more than 80 thousand records and i need to export in .csv format.
I need to export to woksheet.
I need to export nearly 65 thousands of records in one sheet,

I'm exporting data to Excel but where the currency values are formatted I get an  before the currency symbol.

URL...I now want to turn off all hyperlinks that are in the gridview. How do I do that with this code?
Button on page<asp:Button ID="Button2" runat="server" Text="Export to Excel"
OnClick="BtnExportExcel_Click" Font-Names="Arial" style="text-align: center" />
Code behind: Public Overloads Overrides Sub VerifyRenderingInServerForm(ByVal control As Control)
' Verifies that the control is rendered
End Sub
otected Sub BtnExportExcel_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click
[code]....
What am I missing because when my gridview exports the Area (DataTextField) column still has the links although I have a function to remove the links:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="SqlDataSource1" EnableModelValidation="True" Width="856px" CaptionAlign="Top" Height="126px" BackColor="White" BorderColor="#DCBE68" BorderStyle="Solid" BorderWidth="1px"

I need to export asp.net page toexcel 2007. when i wrote the code as below:

Response.Charset = ""; Response.ContentType = "application/vnd.xls"; System.IO.StringWriter string
Write = new System.IO.StringWriter(); System.Web.UI.HtmlTextWriter html
Write = new HtmlTextWriter(stringWrite); div1.RenderControl(htmlWrite);
Response.Write(stringWrite.ToString()); Response.End(); }
publicoverride void VerifyRenderingInServerForm(Control control) {
} and
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="poprint.aspx.cs" Inherits="print_poprint" EnableEventValidation="false" %>
It displays message as shown
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.
everyting working fine but with this below query only numeric value getting from excel and saving into sql database String value not getting from excel?

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:

Is it possible to redirect to another website after Exporting a datagrid to Excel?
Right now I have code that goes a little something like this
Response.ClearHeaders();
Response.ContentType = "application/ms...";
/* write to an Excel file through streams */
Response.Redirect("newpage.aspx");
That is the basic idea of my code.
This doesn't work because I can't redirect after clearing the header or changing the content type.
In my application i have gridview that I export it to excel. When exporting I have the option to select if show the data with images or with no images. The application run well, but when i try export Hebrew data I got gibberish letters. The second thing is that if I select the option "with no images"
Sometimes the Hebrew seems good, and sometime not. Of course I add the Response.ContentEncoding. I thing maybe I should encoding one of this rows

I have created an Excel 2007 spreadsheet using DocumentFormat.OpenXml.Spreadsheet. This file is supposed to be used as an attachment to an email message. However, I get errors when opening it stating that this file cannot be opened by using Microsoft Excel. "Do you want to search... online..?" I want to save this file in Excel 2003 format so I won't get that message. What do I do? I don't want users having trouble reading the attached Excel doc.
View 8 RepliesI need a way to export data from MySql database (or simply from DataTable) to Excel and set colors of particular rows based on one of the fields' content.

I currently have a data grid that exports to Excel on an ASP.NET page (which is used for reporting purposes) which works great until we put it under the stresses of a full scale production environment. With a multitude of users using it it seems to fill up the server memory quite quickly since the data thats being pulled is rather large. The requirements of the page are: The data needs to be queried and exported to excel, so theres no point to getting around that. I've noticed that xls files are rather large in comparison to their xlsx counter parts, using xlsx files would be fine for my application. I've noticed that xlsb (Excel binary) are even smaller(approx 25% the size of the their xls counterpart). Is there anyway to change my code to export to xlsb (first choice) or xlsx rather than xls? I think it has something to do with Mime Types but I'm not positive.
Here is the code that I'm using for exporting:
