In my site I have no App_Code folder, no Bin folder, no codebehind files, and no web.config. I need to make a form that exports an Excel spreadhseet filled with database results. Anything I do has to run out of the inline script runat="server" block at the top of the page.
View 2 Replieswhen I used a code of exporting gridview into excel this code worked for a new website which is without masterpage.
my code:
public override void VerifyRenderingInServerForm(Control control) { }
protected void BtnGenerateReport_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition",
"attachment;filename=GridViewExport.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();.....
Now the same code when I copy it in my project having masterpage . there is no compiler error but it is genereating excel file withno data in it but in fact there is data in the grid view at runtime.
Are there any good PHP libraries for exporting data to Excel files (not CSV files)?
(An alternative would be creating an ASP.NET Web service that handles Excel file generation, but I would rather not send complex objects over a network in XML format, unless it were strictly necessary.)
I currently have a page which displays a report of multiple tables with the data values in them based on two parameters selected in dropdowns.
Now, I need to generate the same report for each combination of the two parameters as a worksheet in an Excel workbook to be sent as an email attachment. This is to be automatically generated daily, and I'm using the Global.asax to do this task at 1 day intervals. So each sheet will display multiple tables, one below the next, just like they display on the web page where the user can go to view them on demand.
I've seen plenty of resources for exporting a gridview to Excel, where a user clicks and is prompted to download an Excel file, but this is different.
I am using following code to get the columns from excel into datatable. In that in my excel file columns started from C to E means columns A and B is blank(Headers also). When i am reading excel file into datatable that time it's taking columns C to E. I want A and B also.Means when i am reading file that time blank columns are avoiding. I want blank columns should be read.
Excel File Data:
A B C D E
1 2 3
5 6 7
And in Datatable i am getting:
C D E
1 2 3
5 6 7
So i want Columns in Datatable also just like excel.

View 4 RepliesI am trying to write a bit of code that will export the current contents of a gridview to an excel file on the local system. I've looked at several examples on how to do it and implemented it. However, i am unable to get the gridview to export the data.
Here's the basics of what i am doing:
I'm using httpcontext.current.response to specify the file contents and filename. creating Stringwriter and htmltextwriter objects.
then rendering the table into the htmlwriter then rendering the htmlwriter to the response.
however, regardless of how large or small the table i am working with is, i keep getting the following error:

Visual Studio opens a file called ScriptResource.axd and the error is noted in the following section of code at the throw error line.

I have included the Public Overrides Sub VerifyRenderingInServerForm(ByVal ctl As Control) method as suggested by others but this has not resolved my issue. I am not sure how to proceed.
I have pretty much followed this thread Export to Excel from a Repeater?, however, I get an exception saying
155|error|500|Control 'XXX' of type 'LinkButton' must be placed inside a form tag with runat=server.|
The LinkButton is defined in the HeaderTemplate, so how do I fix this problem?
Updated: The form tag is in the master page with runat="server"

I'm currently developing a program using ASP.NET 2.0 (C#) and i am using Reporting Services 2005. One of the report requirements is to export a data to an excel with multiple excel sheet.
Is there other way to generate multiple excel sheet using the reporting services? if yes, i would like to ask a sample code..

the dtresults is a datatable that is created on the page. the problem i have is if the cell has commas in like '12 london road, london, le126yr' in the database then its putting it onto the next line in the exported csv file and treating it as a carriage return rather than keeping all on the same line. I have done a replace in the code to replace the comma's to replace them with nothing but it doesnt seem to be working.

Its like in new window it shows loading for more than 10 min and after some time the particular window gets closed and nothing happens can anyone tell me what can be wrong.When the same code works great when i export to 2003.
I've created a function that takes a datatable and exports it to excel by creating a Table.
When the file exported excel says "this file is in a different format than it's extension, do you wnat to open it anyway?". I'd like to get rid of this message if I can. and...There is an extra row at the top of the the excel file (row 0) and it's empty.

i have datatable with data i want to export or wite this data to excel file
i have some thousands of rows in datatable
but i want not use Response.Output.Write
I have been asked to create import functionality in my application. I am getting an excel worksheet as input. The worksheet has column headers followed by data. The users want to simply select an xls file from their system, click upload and the tool deletes the table in the database and adds this new data.
I thought the best way would be too bring the data into a datatable object and do a foeach for every row in the datatable insert row by row into the db. My question is what can anyone give me code to open an excel file, know what line the data starts on in the file, and import the data into a datable object?
I've been working on this for a while and everything that I have read seems to tell me to use the same setup. I have been able to export the data to an xls file on my local C drive but that won't work when hosted on the server as I'll want users to export their data to their local machines as well... I guess the issue I'm having (or at least what I think am having) has to do with my response.end() function. I'll give you my code that works and the one that doesn't... In the end they will both do the same thing...Here is the code I've been playing with for my button:

Now here is where it will at least save on my local drive via a button in my drop down menu:

I need to prompt the user to save the file to a location and perhaps be able to name the file etc
I have a file that I need to copy, run a command against the copy that specializes it for the person downloading it, and then provide that copy to a user to download. I'm using ASP.Net MVC2, and I've never done anything like this. I've searched around for the simplest way to do it, but I haven't found much, so I've come up with a plan.
I think what I'll do is generate a guid, which will become the name of a folder I'll generate at the same level of the source file that the copy is made from. I'll then copy the file to that folder, run my command against it, provide a link to the file, and I'll have some service that runs every now and then that deletes directories that are more than a day old.

View 6 RepliesI need to be able to generate a basic CSV file of the results returned from an SqlDataSource/GridView upon the user clicking a button, then allow them to save this file.
Is this simple to do?
I have a client that is looking for a photogallery in flash, they already have one in mind they found. Since the site will be maintained by them, i was wondering if there is a way to generate an XML file via a button click so when they are logged into the admin console, they can update the XML with a simple click and it updates the gallery.
I will be giving them the ability to upload images to the site as well as deleting and updating existing images, so once they have done all that, they can click a button and that takes all the new updated images in the directory and generates a new XML file for the flash file to use.
Or is there another gallery i can use to give them the same look? This is the gallery they found and like: [URL]
