Asp.net - Exporting Gridview Contents To Excel Spreadsheet?
Feb 25, 2010
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 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 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'm trying to export the content of a data grid to an Excel file. But here is my problem:
1. If I use a Data Grid which was set to allow Adding and Editing of columns ( this appeared the first time I add the control to the form) , the resulting excel file will show all the content of the data grid, except for the Headers ( Column names) .
2. If I use a Data grid which was set to disabled adding and editing of columns, the resulting excel file is lacking the bottom-most row of the data grid content. The Headers are also not included.
I cannot choose Option 1, since the data grid must not be editable by the user. I cannot choose option 2 since the last row is being omitted. Another thing is that the Column Names ( the data are coming from a MS Access File) are not added into the Excel File for both Option 1 and 2.
Here is the code I'm using. I found it from the net and tried changing the values of i and j but still I can't get the result I wanted.
For i = 0 To dgreport3.RowCount - 2
For j = 0 To dgreport3.ColumnCount - 1
xlWorkSheet.Cells(i + 1, j + 1) = _
dgreport3(j, i).Value.ToString()
Next

I 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"""

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 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 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

"C: est estfile.xlsx"
[Code]....
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.

i need to export a query result to excel. I did it using a few methods but it seems that it is taking to long if loading large amount of data like 1000 rows. I did looping a datatable and write the values to excel via excel object 11.0. - 20 secs for 1000 rows exporting the data to CVS but i will have problems formatting the data. using copyfromrecordset using adodb. But they want it to be done in .net Are there any better and faster ways? Must be done programmatically using vb.net.

I'm exporting datagridview data to Excel via dataset.Col 1 of my datagridview contains dates and the grid shows the dates w/o time.Once exported the dates to Excel, they are then formatted via wSheet.Range("B:B").NumberFormat = "ddMM"..The above code works fine for dates having a single digit day. For days 10 and above, the dates are shown as dd/MM/yyyy 00:00 in the excel sheet.[code]If days are single digit, month is swapped with day when writing to Excel from a dataset.

I have been trying to export a DataTable to an excel file and have been hitting a few wallsI am using Visual Studio 2010, VB.Net, Windows 7 64-bit, Office 2010 32-bit. 1) I first had trouble with not closing the Excel.exe *32 process and solved that by using the FinalReleaseComObject(ExcelFile).2) When I use the FinalReleaseComObject, it re-checks the "Ignore other applications that use Dynamic Data Exchange" under Excel's Options-->Advanced. Then any time I try to double-click on an Excel file, I get the error: "There was a problem sending the command to the program." Excel opens, but the worksheet I want does not. The only solution I have found to this problem is to have the DDE unchecked
Private Sub PrintTable(ByVal data As DataTable, ByVal FileName As String)
Try
Dim priorSum As Integer = 0

I have a vb6 app that creates an Excel 2003 doc that I need to export to pdf. I have the following code to export,
excelWorkBook.Worksheets.PrintOut Copies:=1, ActivePrinter:="Adobe PDF",' printtofile:=True, prtofilename:=strOutputName
but nothing prints. The app exports to pdf works in test, but not when I move it to production. I have to remote into the machine that runs the app, so my printers from my local pc are "attched" to the remote session, can this have something to do with no output. The remote machine does not have the Adobe print drivers installed.
What can I do to get the export to work?

i have a dgv populated from a csv file and i am filtering the dgv further and exporting it to the excel. But my problem is it is exporting all the values from the original dgv not from the filtered dgv. I am using one dgv and 2 buttons in my form. When I click the button 1 my dgv gets filtered . when i click the button 2 it must export the filterd dgv to excel but it is not in a way as it is supposed to be instead it exports the unfilterd dgv (all the values from the dgv)

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.
