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.
Dim attachment
As
String =
"attachment; filename=Awards.xls"
System.Web.HttpContext.Current.Response.ClearContent()
System.Web.HttpContext.Current.Response.AddHeader("content-disposition", attachment)
System.Web.HttpContext.Current.Response.ContentType = "application/ms-excel"
Dim sw
As
New StringWriter()
Dim htw
As
New HtmlTextWriter(sw)
gv.RenderControl(htw)
System.Web.HttpContext.Current.Response.Write(sw.ToString())
Dim STYLE
As
String =
"<style> .text { mso-number-format: ; } </style> "
System.Web.HttpContext.Current.Response.Write(STYLE)
System.Web.HttpContext.Current.Response.[End]()

How do I do that with the code?

I have a string coming from a stored procedure looks like '001234567'.
sqlCommand = new SqlCommand("csp_Bbp_OBN_GetBasePageList", BBConnection);
sqlCommand.CommandType = System.Data.CommandType.StoredProcedure;
sqlCommand.Connection.Open();
// Run the SQL statement, and then get the returned rows to the DataReader.
accReader = sqlCommand.ExecuteReader();............
In my case, from the stored procedure I am returning the varchar, after executing and reading it I am getting the value to basePage.GrouNum which is a string. So, I don't see where it is trimming the leading zeros.
Example: GroupNumber in the table is : "001234567"
BasePage.GroupNum after reading from DataReader : "1234567"
But, I do not want the leading zeros being trimmed.

I have understood there is no way to keep leading zeros in a OleDbDataAdapter?
Im trying to read some data from a text file with:
MyCommand = New System.Data.OleDb.OleDbDataAdapter("SELECT F7, F5, F9, F1 FROM " & System.IO.Path.GetFileName(bonnerfil.PostedFile.FileName), MyConnection)
I have managed to keep leading zeros if I add a Schema.ini file into the directory with column set to Char.
But, when having a Shema.ini the select statement reads from start to end of the file. As you see in my select statement I prefer/must have the coulumn 7 first being read and so on. This do work and I will have get the result I want. But for now it´s either - get the order of columns correct or have leading zeros.
how can I either have a Schema.ini that reads the file in the order I want, or keep leading zeros and not have the order I want.

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.
Here is my code:

I've been working on this for a while and everything that I have read seems to tell me to use the same setup. I have been able to export the data to an xls file on my local C drive but that won't work when hosted on the server as I'll want users to export their data to their local machines as well... I guess the issue I'm having (or at least what I think am having) has to do with my response.end() function. I'll give you my code that works and the one that doesn't... In the end they will both do the same thing...Here is the code I've been playing with for my button:
[Code]....
Now here is where it will at least save on my local drive via a button in my drop down menu:

I need to prompt the user to save the file to a location and perhaps be able to name the file etc

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 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 don't want to export the whole GridView because I need a way to add fields with calculated values as needed.
I have the following code that works:

But I don't know how to set colors to particular rows. Also, I don't know how to make Excel treat text fields that look like numbers as text to avoit scientific notation.

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:

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.

I 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">
<AlternatingRowStyle BackColor="Gainsboro" />

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?
