Exporting Data from Gridview to a excel spreadsheet? How do I do it? I google for examples and all the examples I found are for ASP.Net but I am doing a windows app using vb.net.. Is there anyone that can provide me any example of exporting data from gridview to a excel spreadsheet?

I am trying to create double and number format cells in excel using NPOI library. I used code like Dim cell As HSSFCell = row.CreateCell(j) cell.SetCellValue(Double.Parse(dr(col).ToString)) In excel numbers are aligning right but when I check format it is showing in "General" then I changed my code to like below
I have a datagrid and one of the columns show the size of a file.
Ex: 87 bytes 978 kb 500 Mb 766 Gb
If i get the number of bytes, calculate the correct value (in kb, Mb or Gb) to show as you can see above and add the value on the cell, it works but when i try to sort the column it does not work. It get's the wrong order.How can i format a column on a grid view so the sorting works correctly?
Having a problem with Gridview losing it's column width, font, headings, etc when attempting to change font/color when null fields exist.
Here's my code that works correctly
HTML
'>>==== Highlight a Row after grid is sorted ====== 'can be used to show 'over budget' items highlited in Red Italics For i = 0 To DgvGrid.Rows.Count - 1 If Not IsDBNull(DgvGrid.Rows(i).Cells("BudYtd").Value) Then 'Only test Non-Null Values
I have a gridview with autogenerated columns that I set programmatically I want to format the column width. This is my code for my gridview in code behind...

I am trying to format the width of my gridview columns dynamically for easy of use in editing and updating. Is it possible to have multiple column widths defined? Here is the code I am using to create the gridview...
protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack)
I have created a Stored Procedure in SQL which produces a pivot table. I've successfully created a GridView in ASP.NET to display this data.
However, some of my column headings are dynamically generated from the data (AutoGenerateColumns=True), and those column headings are just dates, so they will look different almost every time the table is generated.
This all works fine, except that the date format of the column headings is wrong. I know I could change the way SQL produces the dates in its output, but I don't want to do it that way. I want to control it from the web page.
I didn't think this would be difficult - I thought I could just do something along the lines of finding the cells in the header row and changing the datastringformat. The problem is that whether I put my code in the GridView's DataBound or RowDataBound event, the cells in the header row seem to be empty, so I can't reformat them. It's as if the headers get populate some time AFTER the DataBound event, but I don't know when or how to trap it.
I am putting together a kind of "build your own report" page that will have up to 20 options for people to select.Each option, selected by checkbox or dropdown (probably) will add on to the SQL data source to pull only the information needed and display it in a gridview.For instance, the initial query is:
Select C.Name, From Clients as C
[code].....
How can I do this, preferably referring to the column using the column name of "My Position" and not a numeric...If this can NOT be done....The other option is to query everything and format it - and then hide columns in the gridview based on items that are not checked. Would this be easier? (Doesn't sound as efficient to me).
I have this issue that occurs with me and driving me crazy i have a report that contains thousands of records and i need to export it to excel , but the excel normal extension .xls
is showing missing records at the end of the file , so i save my file as an .xlsx extension it saves correctly but when i open the file it generates an error
"Excel cannot open the file '<var>filename</var>.xlsx' because the file format for the file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file."but when i test the file i drag it and open it in an empty notepad all the records shows up correctly
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!

I've got a stored procedure that right now generates a gridview. From that gridview, users want to be able to click on a button, and export it to Excel, where they can manipulate etc locally.But I used this
Dim sw As System.IO.StringWriter = New System.IO.StringWriter Dim hw As System.Web.UI.HtmlTextWriter = New HtmlTextWriter(sw) gv.RenderControl(hw) Response.Write(sw.ToString) Response.End()
and from that I get a message every time it goes to excel,"The file you are trying to open,'Defauly.xls', is in a different format than specified by the file extension. Verify that file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?" Users don't want that message.. but I can't find any way of getting rid of it.any solutions that does not involve tinkering with system registries (it's not feasible for this project)?
My other option is to convert the gridview to a datatable, and have another process do the export. But I'm stuck on the part where I dynamically create the columns and column names from the gridview (or stored proc for that matter).. . it won't always be the same amount of columns etc, so I can't hard code that in.
I'm getting the following errorError: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.I want to put the grid in excel onclick

I have a requirement to allow users to browse directories on our file server, and allow the users to navigate to an excel file open it, potentially update it and save it. I have it working. I have 2 gridviews - the first binds to an array of DirectoryInfo and the second binds to an array of FileInfo. I render the name of the file as a link in the grid, like this:
a href='file:///<%# Eval("FullName") %>' target="_blank" >'<%# Eval("Name") %>'
When the link is clicked, the excel file is opened within a browser. In order to save, it seems they have to do 'save as...' and it's confusing. Here is where my questions are. What's the difference between opening an excel file within a browser, vs. opening it with excel? Can I have a link to the file in my grid as above, but cause it to open using the Excel application instead of the browser? Does it matter that the excel files are on a file server? I think my users would be more comfortable editing the file within Excel - not in the browser. How can I accomplish this?
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:
Protected Sub ExcelButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ExcelButton.Click Response.ContentType = "application/vnd.ms-excel" Response.Charset = "" Me.EnableViewState = False
[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.
I have a VB.Net application and once the data in the Gridview is populated I require it to be exported to an Excel sheet. Access (.MDB) is the database used.
