Export A GridView To Excel?

Mar 30, 2009

I would like to export a GridView to excel, which is easy enough. But above the grid, in Excel, I would like some other information for identification. Can I somehow export things other than gridviews while then putting in the gridview below?

Edit:For some reason when the GridView1 is visible and I try to export, the entire page exports and not just the gridview. Not sure why!

Protected Sub btnExport_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnExport.Click
'Create a StringWriter and HtmlTextWriter
Dim sw As System.IO.StringWriter = New System.IO.StringWriter()[code]....

Zip Code Is Dropping Leading Zero When Displayed On Excel. Export To Excel From XML To XSLT Transform?

Aug 16, 2010

I am exporting data from vb.net to excel and it is dropping the leading zero when its displayed on excel. How can I avoid the dropping of leading zero? I read the solution of adding a single quote but it makes my excel sheet column ugly. Also users will complain if they see a single quote on zip code field.vb.net code

Response.AddHeader("content-disposition", attachment)
Response.ContentType = "application/vnd.ms-excel"
Response.Charset = ""

the stored procedure outputs XML and it is transformed by XSLT before it is displayed on EXCEL

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<HTML>

[code]....

adding a single quote or manipulating excel sheet with column formatter (general/numbers ) etc. I don't want user to make any changes on excel to get the display properly when the excel is displayed from web page it should be all set with proper formatting. also we have no control over client excel software?

.net - Exporting To Excel Removes Leading Zeros. Css Styles To The Table Does Not Carry Over To The Excel Export?

Aug 4, 2011

I have an asp:table which I want to exported to excel. One of my fields are alpha numeric and when exported to excel the leading 0s are stripped off. After going through this thread: Validation (CSS 2.0): 'mso-number-format' is not a known CSS property name I would like to use the css method "mso-number-format:@;.But the css is not exported to excel. I just tried to test it with simpler css things like bold font etc but its not getting carried over. I can see that if I surround my asp:Label with tags this change gets carried over to the excel but not the css bold . Other solutions in other thread does not work for me as ="00111" shows up as desired in excel but in the web form it shows up as ="00111" which is not what i want.

Asp.net Using Oledb To Export Excel File Returns Empty Excel File

Feb 24, 2010

I am using asp.net oledb to export information to excel file. I encounter problems when the information to export becomes too big, in this case the code I have given below, the excel file generated becomes an empty spreadsheet.If I changed the loop to 1123 for insertion of the rows. The generated excel file is fine, 1125 rows, and 4 columns shown.A test program in windows form is also working fine regardless of how many rows.[code]I couldn't find a solution to my problem as well. What I did eventually was to run the process using another separate windows service. The code works perfectly fine running from a windows form or service program, but not asp.net, not sure why.

Excel Export In ASP.NET + .NET Bug?

Mar 20, 2009

We use a small bit of excel exporting code in our app code at work to export XML controls from our ASP pages into an excel format using the following code:

Public Shared Sub Export(ByRef xml As Xml, ByVal filename As String)
Dim response As HttpResponse = HttpContext.Current.Response()
response.Clear()

[code]....

This is all fine, except we've encountered a rather frustrating bug. If the XML control has a link in it then the export code is called again. We have a button which will say "Export to Excel" from the .aspx page which simply calls ExcelExport.Export(Xml1, "MyFileName") which is in a LinkButton click event.Here's the order of events based on the form submit (selecting filters)

Enter filters
Submit form
Page_Load occurs

[code]....

So the user submits a form which loads up the XML control in a nice viewable XSLT page. Then they click "export to excel" which will give them the page in excel instead, then they click on the XSLT page, for example a link, but the save dialog for excel comes up again. We've gone through the series of events, and if we do not call the excel exporter it goes through the series of events as normal. If we do call the excel exporter it will go through the page load event and unexpectedly go into the link button click event.
