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 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.
The control GV2 is in fact inside:
<form id="form1" runat="server"></form>
I am trying to gather some information about exporting data contained in a datagrid to an excel spreadsheet. I am not using ASP. The number of rows and columns are not set(fixed). If someone was able to point me in the right direction or even better a quick example. I have search through previous threads and am unable to find any that relate to exporting from a datagrid on a windows form to an excel document.

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.

View 5 RepliesI 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.
Just wondering if i might hit a snag in my program. Ive got 10+ users using the same files, via a Oledb to put info into an excel spreadsheet. If 2 or more people save there file at the same time will the program go into read only on one person. Normally one 3 will use the file at one time. I know Sql itself would be better to use. best way i can describe it, normally using excel if you manage to open the same file twice one opens as normal but the other opens as a Read only file, will the same thing happen if im using Oledb connections?
View 2 RepliesI 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).

FirstName

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"">")

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 wanting to try and develop a form that will allow me to import an excel spreadsheet in to a datagrid view, can do that bit with this, Vb.net Information. what i want to be able to do is select which columns in the spreadsheet go where so say i have a spreadsheet with;
ProductCode, ProductName, ProductDescription, ProductCost and ProductMaker
In my DataGridView i have ProductName, ProductCost and ProductDescription.Is it possible to get a list of the columns in a spreadsheet that have text in and then either have a combobox that you select a value from and then after pressing a button it then imports the selected details in to the correct format, (Like mail merge)

View 4 RepliesI'm trying to import an excel spreadsheet to a bound datagridview. I have a second form which I do all the importing from and update Form1's datagrid view. This part works great. Now, I am trying to update the table that the DGV is bound to, but cannot seem to get it. I know it is probably a simple Update command (which I've tried) but everything fails. It is confusing to me because I create a second dataAdapter and dataSet to import to, then set the BindingSource of the DGV to this new ds. Ideally, I want the Bound table to be empty, then require the user to import on the first run. After that, the imported list would always load.
Here is the code I use to import to the DGV and it works:
vb.net
Dim ds As New DataSet
Dim da As OleDbDataAdapter
Public Sub importDBButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles importDBButton.Click
OpenFileDialog1.InitialDirectory = ""
OpenFileDialog1.Title = "Select the Excel File to import from"
OpenFileDialog1.Filter = "Excel(*.xls)|*.xls"
[Code] .....
My DGV on the first form has a manually added column at index 0 that is a simple graphic. Not sure if this is causing errors, but thought I'd mention it. The spreadsheet that is imported is only 2 columns of the DGV. Do I have to specify data for the other columns? (There's about 16 and I didn't want to have to require the user to fill all that data out in the spreadsheet). How to save this imported data to the bound table?

View 1 RepliesI have a VB.Net program that reads in a flat file, and then parses line by line, formatting the data into different spreadsheets in an excel workbook (each line can be any 10+ different record types so I parse and put in appropriate excel sheet).
For smaller sized flat files (under 10mb), the parser works great. However, I am trying this on a file that is over 120mb (400k+ lines). While running, I will get an OleDBException saying that the spreadsheet is full. Now I am pretty confident that Excel can handle a much larger data set than a flat file. So I assume this exception is not giving me the true story as to what is really occuring.
I open a connection, and then parse each line in the file, inserting each row into the excel file. I assumed it would be bad performance wise to open/close the connection between each insert. Could this be causing the issue? Any ideas what I need to do to handle such a large file? There are cases where the flat file can be over 500mb.
To actually do the insert into excel, I am just doing the following (I construct an sql query based on the type of row and values parsed):
Dim conn As New OleDbConnection()
conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + ExportLocation.Text + "" + importFileName + "-PVF.xls;Extended Properties=""Excel 8.0;HDR=YES"""

It's been about... er, how many years since vB5 came out? Since I wrote my most recent project, so I'm struggling to remember things and get used to the new VB2010 environment.
I am trying to figure out the best way to go about pulling information out of a table.
Top row: Mileage of a vehicle
Left column: Year of a vehicle
The data it would then spit back out is the maximum term a bank will finance a vehicle based on year and mileage.
What would be the best way to pull that data? I'm thinking the easiest way to maintain the data is with an excel spreadsheet that is called by the VB app to pull the data, but I've never had to pull data in this format before.
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.
View 2 RepliesI 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.
