Forms Data Controls :: How To Determine Excel .XLSX Version From Uploaded File

Aug 10, 2010

In my application I've allowed users to upload Excel 2003 .xls files, and import them into a Gridview. This has been working fine using the following connection string:

[Code]....

Now my users are using Excel 2003, 2007 or 2010, I need to allow the newer file extensions (.XLSX) to be accessible too.

Therefore, within the connection string above I presume I could change the Excel version from 8.0 to 9.0 or 10.0 respectively, but is there much difference between Excel 2007 and Excel 2010 files?

If so, is it possible to 'detect' the Excel file version so that I can use the appropriate connection string to read the data from the files?

Visual Studio :: Exporting A .rdlc To Excel / Analagous Export Of That Report To Excel?

Nov 2, 2010

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.

C# - NPOI Excel Number Format Not Showing In Excel Sheet?

Aug 6, 2010

I am trying to create double and number format cells in excel using NPOI library. I used code like

Dim cell As HSSFCell = row.CreateCell(j)
cell.SetCellValue(Double.Parse(dr(col).ToString))

In excel numbers are aligning right but when I check format it is showing in "General"

then I changed my code to like below

Dim cell As HSSFCell = row.CreateCell(j)
cell.SetCellValue(Double.Parse(dr(col).ToString))
Dim cellStyle As HSSFCellStyle = hssfworkbook.CreateCellStyle
cellStyle.DataFormat = HSSFDataFormat.GetBuiltinFormat("#,#0.0")
cell.CellStyle = cellStyle

Then While opening file it is giving error and also taking so long to open. But Excel format showing in "Number" error showing is like below.

Export GridView To Excel Without Losing Grid Lines In Excel?

Mar 4, 2010

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.

C# - Remove Password From Excel File -- Without Having To Install Excel On Servers?

Jan 12, 2010

I need to remove the password protection from an uploaded excel file. I have been doing this directly with the Excel assemblies (ASP.NET/C#) and then I tried with the ooxmlcrypto, both worked, but the problem is that I can not deploy either of those solution because of the dependencies.

I mean, my sysadmin does not want us installing Excel on the server and, as I have been searching for some alternatives, I can not find one.

My question is: is there a way to put the necessary dlls in the server without installing Excel or the Office suite?

I found this: Office 2007 Primary Interop Assemblies redistributable package but still, it requires a Microsoft Office Product.
