Exporting DataGridView To Excel File?
Aug 25, 2009
I have a a DGV with the following fields:
FirstName
LastName
Address
Job
StaffNum
Nationality
DOB
Notes
Picture
FileName
Now my DGV has records in it and I try to export it to Excel File. Now it exports the the Column Names above but none of the records. My code is below.
Dim fs As New IO.StreamWriter("C:exported.xls", False)
fs.WriteLine("<?xml version=""1.0""?>")
fs.WriteLine("<?mso-application progid=""Excel.Sheet""?>")
fs.WriteLine("<ss:Workbook xmlns:ss=""urn:schemas-microsoft-com:office:spreadsheet"">")
fs.WriteLine("<ss:Styles>")
[Code] .....
I got this code from the MSDN forums from a link someone posted. They said they changed IntCol and it worked to incoude the records as well but I cant figure it out. When I hit Export it does prom,pt me to save the file and saves the Names above to excel sheet but none of the records.

I have a datagridview(DGV) which contains data based on a user selections from a pre-defined dataset
In point form:
User starts program
program builds datatable
user opens file and program read all data from file into the dataset.datatable
user defines the data they want to see
program displays datagrid based on dataset.datatable and user choices. (basically it displays the whole dataset and removes unwanted columns
ecords)
I want to be able to export the datagrid to excel (not sure which method yet). I have tried the excelexporter component i found somewhere on the msdn forums (it exports the data to look exactly like the datagridview) but its painfully slow. It exports something in the region of 100 records per minute. Most of the time, the datagridview can contain anywhere from 3000-32,000 records. As such, at 100 records per minute, the excel generation can take updwards of 50minutes. Unacceptably slow for the purposes of the program.
What do people recommend as the best method to quickly dump the contents of a datagrid into excel. By quickly, im talking at the speed of about 10,000 records per minute. In all honesty, anything over 5000 records per minute will be fast enough, but the quicker the better!
Is there a way of creating a new dataset.datatable that is built of the contents of the datagridview and then building an excel sheet by connecting to the new dataset?
I would like to be able to export to Excel 2000-2003 at a minimum, but if i can do excel 97 as well it won't hurt.

I am filling a datagridview with very lengthy results. Roughly 60k rows on average. I am filling them via an oracle database using a table adapter. The records then have a filter placed on them in the datagridview so the results displayed are a bit different.
My problem: I built an export to excel function which populated a dataset and then red through it and wrote to excel. Bad idea with the amount of records I am using. I tried just writing the records straight to a csv file using streamwriter but I don't very much like this way.
My proposal: I would like to fill an array from the datagridview and then be able to dump the array into excel. However I am having some trouble finding examples on creating an array from a datagridview.

I am using Visual Studio 2008 and looking for an efficient and hopefully straightforward approach for exporting data from a DataGridView to Excel. If doable, my preference would be to export the data to Excel without instantiating an Excel application. I found some code on the Microsoft support site that is fairly accessible but the example shows how to export just a few pieces of data. Would someone be able to demonstrate how to modify this code to so that it could be used for large amounts of data (for example, data from a DataGridView).
'Establish a connection to the data source.
Dim sConnectionString As String
sConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" & _

I have a datagridview which I would like to be able to export the information to an Excel spreadsheet, and be able to reload the information later on from a specified worksheet. Also, I'd like to avoid using Databases with Access etc because I am aware that some of the machines I'll be deploying the program on do not have Access installed and would not want to have to install it either.

I already exporting contents of my datagridview to excel and word but I need to format one of the column of my datagridview. That column is "Amount". In my datagridview, it displays like this "122234". I want to display all the value in that column in this format: "122,234.00". I already tried to format it to number("N") in my datagridview but when I exported it to excel and word, it shows no format.[code]

I need to export the contents of DataGridView into an Excel file. There is lot of discussion which I went thru and leaves me more confused now than before. I am using VS 2010 Express with Office 2007.
In the VB project reference components, I looked for Office components and did not find it there.

I have a DataGridView that I'm loading into Excel through the use of an ADODB.Recordset. It works fine, except for a column I have that displays the time. Not the current time, but the time when a file was sent. It displays correctly in the DataGridView but displays 12:00 AM for every row in excel. I'm adding it to the DataGridView like this:

I am writing a program that uses several textboxes that a user will fill in and then click the add button to add the data into the datagrid. There is no backend database or anything. Just seeing the data in the program only.
What I want to do is then export this data from the datagrid into a file, preferably excel.
I've done copying textbox data into txt files but I can't find a method to copy datagrid data into a file.

In my application I'm exporting an Excel file by getting the layout of a HTML page. So, in my codebehind, I'm modifying the HTML layout and inserting itens on it like if it was a webpage. Doing it that way, I don't need to use any external library and, as the data I'm exporting is just a table, I don't need nothing complex to handle it. My question is: there is a way to create an AutoFilter by just modifying the HTML tags? I mean, like if a put a < b>Column Name in the HTML, when exporting to Excel it will become Bold, it is possible to do the same thing with the AutoFilter?

And when two things happen when I try to use this code (which I modified after finding it on another site)
1. Intellisense tells me that MyDataSet is not defined.
2. When I define MyDataSet as

I want to export data from a DataGridView to a CSV/text file. I then also want to be able to load that same CSV/text file and populate that same DataGridView at a later point in time. My information is loaded into columns in the DataGridView. That is, I am not using rows to represent records, I am using columns. As such, I need to load all the data in each column and export this, by column to the CSV/Text file. Likewise, when I load the control from the CSV/text file, I need to load each column with this information.How do you export/import from/to a DataGridView controlHow do you organize the data in the CSV/File

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.

I am building an ordering system for my job. The idea is that the customer will put in a stage name for an item. That stage name is then interpreted by the program.The product id and the amount the customer wants to order is placed in a list box on the form. There are a couple of buttons, ADD, REMOVE, CLEAR, and EXPORT. The user input is handled by input boxes. When the user pushes the EXPORT button, excel should open and list out the interpreted product codes with the corresponding amount to order. I can get excel to open, but I can not get excel to display more than one line. It will display the first product, but then it comes up with an unhandled exception.I can not figure out how to get excel to return down a row and display the next product within the list box.

I am exporting a datagridveiw to excel, this works fine. As of now there are columns and headers that i needed to add to the excel data that did not exist in the datagridveiw. This also works fine, the data is held in cells a2:f2, now i want to take this data in these columns and filldown to the last filled row of the excel sheet. In this example lets say i have 49 rows of information, i want to take a2:f2 and copy it down to the 49 row of the excel form. Below is the entire code of the export process, i have noted where i need this code to go with , i am not sure if i should just use a for loop, which i have tried to no avail.

I need to export data from a sql table into an existing excel spreadsheet (not create a new one) in Visual Studio 2008.
Here is the code I am using:
Dim SecFileName

I get an error saying the external table is not in the correct format. I assume taht means the existing spreadsheet. But I have verified that I have the same number of fields (i.e. columns) as the spreadsheet I am inserting the data into.
