Web Forms :: Export To Excel - Screen Refresh On Completion?
Mar 17, 2010
There are a million examples of how to generate an Excel file from a web page. I've done that and it is no problem.
What I haven't been able to work out is: how can I update the screen to let the user know how many rows were exported?
It seems to me that after you've done your:
[Code]....
then pumped the data our, then done the:
[Code]....
there's no way to cause a postback or do any subsequent server-side or client-side processing on the webpage with the Export button.
I've tried a whole bunch of different methods, but have not found one that allows me to "play on" after the export has finished with the Response.End() call.

What I'm trying to do is fill in a questionnaire, and have the option to not complete it then it automatically saves, once clicked on "Save" button. However, what I want to search for is previously non-completed questionairres.
Would I have a "status" field in the questionairre table to trigger either "completed"/ "non-completed" when the "Save" button is clicked (in the event of non completed questionaires? How is this normally done?? Im sure there are a hundred and one different ways to do it!

I have a web form that contains a GridView, which impliments Search in Grid with a TextBox and Button control in the footer. This works as I have it now. I have also implimented a Export to Excel function. The Export to Excel works by itself if the Search in Grid function is not included in the footer.The Export to Excel function errors when trying to render the Grid for the export. Is there a better way to incorporate both functions and accomplish the same thing? Am I missing something simple?

We have the requirement to export the data from the grid excel. We can't install the Excel on the server. The excel generated need to be in the printable format. The excel generated needs to have custom headers, footers, repeatble rows, columns and landscape / portrait orientation style.

I've got an .rdlc report which I print from my .net app (C# Visual Studio 2005), where I use a RemoteReportPrinter object. I give it as parameters the server name, report name, report parameters, etc. Works fine. My question is, I would live to do an analagous export of that report to Excel. Set it up exactly the same, but have it export to Excel rather than print, probably using some other type of object than RemoteReportPrinter.

We are deveopingawebiste in asp.net. There are tempelates of each aspx page made in the form of excel sheet. Upon completion of the online calculation, the user is to be allowed to export the results to excel and save them. There would be obviously no formulae in such sheet
I do not want to install Excel on theserver and instead want to utilize the Excel installed on the user's computer for this purpose as every user's computer is expected to have Excel installed. Is this possible to do? How to do this?
I am not an expert in this. let me know if you would need any more information or clarification.

I have a GridView that I want to export to Excel. When I use the sample code I find online, it exports the content to Excel just fine, but for some reason it also clears out all grid lines outside of my exported table.
For your average excel user this is easy enough to fix, but I need this solution to work for everyone.
So then is there a way to export the data in a GridView into an Excel Workbook so that it looks like it was just typed into Excel? I've pasted the code I am using below, assume that a GridView called toPrint exists and has accurate data.
Response.Clear();
Response.AddHeader("content-disposition", "attachment; filename=" + name + "_Registration_Forms.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
Page.EnableViewState = false;
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
toPrint.RenderControl(htmlWrite);
Response.Write(stringWrite.ToString());
Response.End();
EDIT: Found one partial solution. If I export as a comma-delimited list and set the header to be a CSV file, it opens fine and all grid lines (even those outside of the exported data) are showing. The only problem with this of course is having to strip out every comma and newline character from my values before exporting them.

Problem: How to display more columns in a Telerik grid than are displayed in the rendered grid?
eg I'd like to only display on the screen the Surname, but on dump to csv would like firstname too.
I've tried visible = false, and display = false on the GridBoundColumns, but then they don't come out on the csv.
<telerik:RadGrid ID="grdAuctions" runat="server" AllowAutomaticDeletes="True" AllowAutomaticUpdates="True"
AllowPaging="False" AllowSorting="True" AutoGenerateColumns="False" DataSourceID="odsAuctionSales"
GridLines="None" EnableEmbeddedSkins="False" OnItemDataBound="grdAuctionSales_ItemDataBound">
<ExportSettings HideStructureColumns="true" />
[Code]....

Actually I have a SQL query that a user exports to excel in our web server. I did it in c# with Visual Studio 2003 (.Net v1.1): I get the data from a SQL server into a Dataset, then with this method I create the XLS file:
private void ExportAsExcelFile ( DataSet dtExport )
{
Response.Clear() ;
Response.ContentType = "application/vnd.ms-excel";
Response.ContentEncoding = System.Text.Encoding.UTF8 ;
Response.Charset = string.Empty ;
Response.AddHeader ( "Content-Disposition", "attachment;filename=data.xls" ) ;
System.IO.StringWriter objStringWriter = new StringWriter () ;
System.Web.UI.HtmlTextWriter objHtmlTextWriter = new System.Web.UI.HtmlTextWriter(objStringWriter) ;
DataGrid objDatagrid = new DataGrid () ;
objDatagrid.DataSource = dtExport ;
objDatagrid.DataBind () ;
objDatagrid.RenderControl ( objHtmlTextWriter ) ;
Response.Write (objStringWriter.ToString()) ;
Response.End () ;
}
Well, this works when the SQL query has 10.000 rows and so on. But now the query has more than 200.000 rows, and I´m getting a TimeOut Error trying to export the data. I read about generate this big files with a Store Procedure and the SQL Commad: BCP [URL], but I tryed and it fails. I have no permissions to execute this command. Is there any other way to export this SQL data to Excel via a ASPX page?

I added a radiobuttonlist to the page and now when I select another radio button from the radiobuttonlist then export to excel I am getting a gridview that says no records. Here's the client side page:
<asp:RadioButtonList ID="Pending" runat="server" AutoPostBack="True"
OnSelectedIndexChanged="Populategrid" Height="16px"
RepeatDirection="Horizontal" Width="755px">
<asp:ListItem Value="250">Pending Over 250</asp:ListItem>
<asp:ListItem Value="300">Pending Over 300</asp:ListItem>
[Code] ....
Here's the export to excel:
Protected Sub BtnExportExcel_Click1(ByVal sender As Object, ByVal e As EventArgs) Handles Button4.Click
Response.Buffer = True
Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.xls")
Response.Charset = ""
Response.ContentType = "application/vnd.ms-excel"
Dim sw As New IO.StringWriter() Dim hw As New HtmlTextWriter(sw)
GridView1.AllowPaging = False GridView1.DataBind()
[Code] ....
What do I add so that when I select another button from the Radiobuttonlist it will then export that to excel?
