Forms Data Controls :: Gridview And Excel As Datasource?
Mar 26, 2010
im using an excel file as a datasource for my gridview...i can pull all the data into the gridview fine. i am now hoping to allow the user to update the data in the excel file through the gridview. is it possible to update the excel file in this format i.e. allow the user the read/update the excel file as if its a database. i see some references in google that its not possible to update the excel file as the writeout causes problems. does anyone have this working...or should i look into trying to use another datasource.
i was hoping to use an excel file as the app is on a shared server and it would be handy just to have the excel file in the app folder as there is not much data involved.

when 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 have a GridView populated by an ObjectDataSource. I also have several DropDownLists filtering the ObjectDataSource. I found a link providing a way to export a DataSet (or DataTable) to Excel here:
http://msmvps.com/blogs/deborahk/archive/2009/07/23/writing-data-from-a-datatable-to-excel.aspx
ow I can ensure that filters applied to the ObjectDataSource when the method is called are applied. In short, how can I ensure what the UI is displaying is what the file will include when exported?

I need to open a GridView as either an Excel or a PDF file. The excell prodecure is working fine, but I'm getting a: File does not begin with '%PDF-' error when trying to use the PDF file. The code is as follows:
Protected Sub EMButton_Click(ByVal sender
As Object,
ByVal e As System.Web.UI.ImageClickEventArgs)
Handles EMButton.Click
'Save the table to an excel File
Dim StringWriter
As New System.IO.StringWriter()
Dim html As
New System.Web.UI.HtmlTextWriter(StringWriter)
Dim form As HtmlForm =
New HtmlForm()
Page.Response.ContentType = "application/vnd.ms-excel"
Page.Response.Charset = ""
Page.Response.Cache.SetCacheability(HttpCacheability.NoCache)
Page.Response.AddHeader("content-disposition",
"attachment;filename=FullDateReport.xls")
Page.EnableViewState = False
form.Attributes("runat") =
"server"
Controls.Add(form)
form.Controls.Add(GridView1)
form.RenderControl(html)
Response.Write(StringWriter.ToString())
Response.End()
End Sub
[this doesn't work]
Protected Sub PDButton_Click(ByVal sender
As Object,
ByVal e As System.Web.UI.ImageClickEventArgs)
Handles PDButton.Click
'Save the table to PDF Format
Dim StringWriter
As New System.IO.StringWriter()
Dim html As
New System.Web.UI.HtmlTextWriter(StringWriter)
Dim form As HtmlForm =
New HtmlForm()
Page.Response.ContentType = "application/PDF"
Page.Response.Charset = ""
Page.Response.Cache.SetCacheability(HttpCacheability.NoCache)
Page.Response.AddHeader("content-disposition",
"attachment;filename=FullDateReport.pdf")
Page.EnableViewState = False
form.Attributes("runat") =
"server"
Controls.Add(form)
form.Controls.Add(GridView1)
form.RenderControl(html)
Response.Write(StringWriter.ToString())
Response.End()
End Sub
I've tried using:
Page.Response.Clear()
Page.Response.ContentEncoding = Encoding.Unicode
Page.Response.BinaryWrite(Encoding.Unicode.GetPreamble())
Page.Response.AddHeader("Content-Length", html.ToString().Length.ToString())
With the PDF procedure, but still couldn't get it to work. I've also tried using inline instead of attachment in the header.

I am new to ASP.NET but have had about a year of experience with VB.Net. Currently I am working on a webpage where I can download my inventory list from a GridView control to an excel spreadsheet. The routine is very straight forward however I cannot get it to stop duplication data in the spreadsheet. When I run my routine it inserts the gridview twice in the spreadsheet, the second one immediately to the right of the first table...
[code]....
It renders perfectly on the page by using the following commands:

I have tried a little bit of everything to stop the duplication and am completely stumped.
