I have a gridvidew (GV2). I want the user to be able to export the contents of this gridview to an excel spreadsheet for offline processing.
Here is my subroutine:
[code]...
On clicking the ExcelButton I get the error message:
Control 'GV2' of type 'GridView' must be placed inside a form tag with runat=server.
The control GV2 is in fact inside:
<form id="form1" runat="server"></form>
I am trying to work through a sample of exporting a gridview to an excel spreadsheet.I found the code below on the internet. I pasted it into a test.aspx page. I need to establish a connection to the NorthWind Database. Or if you have a better example of exporting a gridview to excel, share. Here is the location of the northwind.mdb on my pc: (and is this sample looking for an access database or a sql database...what is the filetype of a sqlserver database?) See code below

I am exporting an ASP.NET datagrid to excel and having an issue with the colors exporting with it. I know in order for the cells color to be exported to excel you must set the background color of the cell. I have several lines of text in the cell, parts of the text are wrapped in a div and the div background color is set. This is the color I need exported. Is there a way to do this? I have included an example below of what would be found in a cell.
<div style="background-color: #b88eb5;>
Random Text 1
</div>
<div style="background-color: #8ccb83;>
Random Text 2
</div>
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.
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 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.
<style> .textmode { mso-number-format:@; } </style><div>
</div>
My code is down

I have the following code to 'save' a GridView on a page as an excel file, but it pops up a dialogue screen asking the user to view or save.

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 trying to export grid view data into excel 2007 i.e. xlsx format. but its giving error.
i am using following code
protected void Button1_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
[Code]....
but not working properly and on opening the file it gives following error "Excel cannot open the file 'ChangeRequestList[2].xlsx' because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file"
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();
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

But don't know how. Here is my application printscreen. and this is my code

I have done this before, and am simply pasting the code that works on other pages to this page, but I cannot seem to get this function to work on this particular page. When Excel is opened after the export, all I get is <div> on line 1 and a few lines later I get </div>.

I am exporting GridView to Excel but keep on getting a pop up "The file you are trying to open, 'somefile.xls' is in a different format than specidied 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 I click "yes" the file opens fine. But why I am getting the pop up at the first place.Also as I have Office 2007 on my machine

I have the following scenario shown below
Label: Name
ID Qty
1 10
2 5
Kindly note, the ID. QTy are currently in a gridview and the Label is a label on top of the gridview. I would like to export both the label and the gridview to excel...how can I do this.
This is an ASP.NET 3.5 project being created with VS2008. One page contains a gridview with six columns. One of the columns displays standard, 17 character , Vehicle Identification Numbers (VIN). The VIN numbers display normally when the page is rendered. However, when the gridview is exported to Excel, the VIN numbers change. For example, in the gridview, the VIN might be 12345678912345678But when the gridview exports into Excel, that same VIN becomes 1.23457E+16The value of that Excel cell changes to 12345678912345600, changing the last two digits from 78 to 00. It does this for every VIN in the gridview table.I did some Googling but couldn't find anything specifically on this issue. Has anyone seen it before? Is there a way to format the column in the gridview so that Excel will accept it as literal text? I tried programmatically adding a style called 'text' to that column but that had no effect on the outcome. All of the other columns are behaving normally.
View 3 RepliesI am able to save excel sheet from GridView perfectly. However, I need to add one custom column, which will be URL of a file on sever, I am not allowed to add URLs directly in the table (as per company's development policies). I tried pulling URL from web.config however I am not sure where to add that in the following code
<asp:GridView ID="bestpractgrv" runat="server" AutoGenerateColumns="False" CellPadding="3" GridLines="Vertical" Width="100%" BackColor="White" BorderColor="#999999" BorderStyle="None" BorderWidth="1px" PageSize="10" AllowPaging="True" OnPageIndexChanging="OnPaging" DataKeyNames="iID">

I finally managed to export a gridview to an excel sheet.
Next, how can I remove the column width and alternatingrowstyle color (or all formatting if it is easier) "programatically" before exporting it to excel?

I am trying to export a gridview that is returned from a search form. The gridview also has paging enabled. In order to export the records from all pages in the gridview I had to turn off paging and do a databind, but instead of only exporting the search results it exports all the records in the gridview.
How can I only export the records from the search results, but also the make sure the records on the different pages export also?
With the code i have below i am able to export only one page of gridview to excel. check and modify it once.so that i can import all the pages of gridview to excel at a time with checked status of checkbox.
protected void btnExporttoExcel_Click(object sender, EventArgs e)
{
DataTable dt = new DataTable();
dt.Columns.AddRange(new DataColumn[5] { new DataColumn("Presentees"), new DataColumn("StudentName"), new DataColumn("ColgRegisterNum"), new DataColumn("CollegeName"), new DataColumn("Date"), });
foreach (GridViewRow row in gvStdntDetails.Rows)

I exported some data from a gridview to an Excel with Images.
I need to give a specified height and width for all the rows and text to be aligned centre.
I realized this has been asked multiple times before, but I still haven't been able to get it to work. I'm trying to export a Gridview to Excel without losing leading zeros. Here is my code. Add added the STYLE lines to try to fix the problem.

I have some code that generates a zip file that contains multiple CSV files and streams it back to the user (no file is saved on the server). However, I want to create an excel workbook instead (can be traditional xls or Office Open XML xlsx format) with each CSV 'file' being a spreadsheet.
How can I do this, without resorting to Office Automation on the server or a commercial 3rd party component?

I my exporting data through dataset to excel. But one column say awb no having datatype nvarchar contains long int no say : 123456789012345.
Then instead of displaying this no in numeric format(123456789012345) it is displaying in exponent form(1.23457E+19).
Is there any way to stop this i want data in numeric format (like this 123456789012345).
