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 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 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 am working on exporting some data to a DataGrid (with no luck). So far I have:
[Code]...
When this runs, I get an error message that says: System.Data.OleDb.OleDbException: The Microsoft Jet database engine could not find the object 'Sheet'. Make sure the object exists and that you spell its name and the path name correctly. The excel file has only one sheet that is named "Sheet", and the location specified in the connection line is correct. Any ideas on why this may be happening?

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;" & _

So I need to create a windows form that is able to generate reports by querying a SQL Database or SQL Server. There is data in the databases that will be put into an excel file from whatever columns from a specific table I need. I need it to be a dynamic query that is probably hard coded into the application because I might need to write other queries at some point to generate different reports that need different columns.
What I need is somewhere to start or some code that I can look at because im not very familiar when it comes to vb.net/excel. I need code to get all that data from the database and put it neatly in an excel file and I would like to specify what columns in the excel file all the data goes under.

I can successfully write it to excel, but how do I get it so each time the application runs it writes the data to the next available row?? I know there must be some loop involved but am having trouble with the coding..
this is what I have so far.

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'm currently trying to import data from an Excel document to a list in Visual Basic 2010 Express. The Idea is to have the data easily modifiable by the users. I have looked quite a bit online and all of the examples seem to reference either an "Imports Microsoft.Office.Interop.Excel" or "Imports Excel". When I try to use the I get "(no correction suggestions)".

I have an project which was written in VB6 and made use of the Spread3.0 component to display multiple large data from database in spreadsheet. My objective is to convert this project into a VB.NET current version which would not use the third party component but can possibly use a freeware that does similar if not all the functionality.
My question is, are there any freeware that is available in .NET for such spreadsheet-like manipulation of data programatically? I have come across dsoFramer but this only allows the display of the data in an IE frame. I would like to jus embed the content into my existing form.
Also this freeware must be able to handle formula and user-editing as well as multiple cell type such as combobox/checkbox etc.
