View 4 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.
I'm working on a project which requires me to plot a graph using Visual Studio ASP.Net from a data I've collected either in .txt or .xml format. The data consist of, eg. 15 records, but I'm only needed to plot 8 graphs out of the 15 records.
View 1 RepliesIn 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.

I 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:
[Code]....
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.
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 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..

View 1 RepliesI have an arraylist that contains some values. (e.g. playerName). I also queried for values in the database (e.g. playerName, playerSales) and I need to match the playerName in the arraylist to the corresponding ones that I did a query from the database. (match those with the same playerName). From there, I need to create a bar graph with the respective playerName and their sales (playerSales).
A portion of the code is shown below:
[Code]....
The arraylist I mentioned was saved to a session to be used in another page. Is my code right? And how can I create the graph from the values?
I have a gridview on a web page as shown below
[Code]....
On checking the checkbox, the user will actually be selecting the products that he/she wants. The selected products will be stored in an arraylist by using a foreach loop through the gridview. The arraylist will then be saved to a session before being redirected to another page. (a button will be clicked after the selection of products to proceeed to another page)
On the redirected page, a bar graph needs to be generated based on the products selected previously and also the product sales (this is retrieved from the database).
How can I generate this bar graph without having to code the whole graph out?
i want to show report in graphical formate of data which is stored in sql server.
View 1 RepliesI have a web page where a GridView will be shown with a column of different products and another column with checkboxes. Checking on the checkboxes will be equivalent to selecting the products. The selected products are saved to an arraylist. Then, the user has to click on a button located on the same page to analyze the selected products. On clicking the button, he/she will be directed to another page where a bar graph will be shown. The bar graph will be the result of having analyzed the products. How do I create the bar graph where the products are taken from the arraylist but I can make use of the datasource within the chart control to retrieve more detailed info(such as product sales) from the database, taking into account the products from the arraylist?

View 2 RepliesI've noticed that page load time increases dramatically as you load up a ddlistbox with items. 10,000 or so results in a pretty much unacceptable wait time for my setup. The dropdown I'm trying to load is Airports - like all of them. What are some alternative UI solutions that give the user the ability to easily select any (literally) airport, but without a ginormous page loading time? (Currently the dd is keyed to the airport's 3 letter code, so it's convenient for the prepared user to just type the 3-letter code and have the right airport selected. The display is then set to code, city, country.)
