I have what would seem like a fairly straightforward task: Export a report (GridView) to a spreadsheet, so that the client (user) can use the data elsewhere. I thought I found a very elegant solution. Here is the code:
Code:
Protected Sub btnWrite2Exell_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnWrite2Exell.Click
Response.Clear()
Response.AddHeader("content-disposition", "attachment; filename=FileName.xls")
Response.Charset = ""
[Code] ...
With a little putsing I got it to work, which is good, EXCEPT that it precedes opening the spreadsheet with a warning that looks like this:
I got an error about OleDB. I just want my excel file import to Gridview. Here is my code.
string connstr = "Provider=Microsoft.Jet.Oledb.4.0;Data Source=C:a.xls;Extended Properties=Excel 8.0;HDR=YES;IMEX=1"; OleDbConnection conn = new OleDbConnection(connstr); string strSQL = "Select * from [Sheet1$]"; OleDbCommand cmd = new OleDbCommand(strSQL, conn); DataSet ds = new DataSet(); OleDbDataAdapter da = new OleDbDataAdapter(cmd); da.Fill(ds); GridView1.DataSource = ds; GridView1.DataBind();
When i build project there is no error but when i run this project i got an error like this:
System.ArgumentException:Format of the initialization string does not conform to specification starting at index 47. Line 21: string connstr = "Provider=Microsoft.Jet.Oledb.4.0;Data Source=C:a.xls;Extended Properties=Excel 8.0;HDR=YES;IMEX=1"; Line 22: Line 23: OleDbConnection conn = new OleDbConnection(connstr);
I am exporting GridView to Excel but keep on getting a pop up "The file you are trying to open, 'somefile.xls' is in a different format than specidied by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?When I click "yes" the file opens fine. But why I am getting the pop up at the first place.Also as I have Office 2007 on my machine

I'm really stuck tryign to figure this out. Converting XLS to CSV is no big deal or at least it seems that way. However, trying to go xlsx to csv seems to be more difficult. For grins, I grabbed some code that is supposed to read a sample xlsx file and convert that into a gridview called GridView1. I figure it can't be much different to turn that into CSV.
How can I export data from a Gridview to excel and once exported the data should be formatted in right to left (arabic) manner. How can I achieve this?
I'm exporting a Gridview to excel. I get all the gridview header and content in excel in addition to that i need to add a header text like report name in header of the excel sheet with line break in header.
I tried the solution in this link [URL] by adding
Table.Caption = "Header Text" Table.CaptionAlign = TableCaptionAlign.Top but i get error Reference to a non shared member requires an object reference.
I am exporting a gridview in MS Excel as mentioned in the following link:

I want to set orientation of excel pages as landscape. Is there any way to do that? Any header information to be added for file being exported to set orientation of pages as landscape?
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 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.
