Export to Excel

maigoro · April 9th, 2008, 08:24 PM

I would like to export my dataview to excel. I have gotten something to work by using asp code but the problem is it send the html file to excel and if there are two pages of data, only the first page is captured. I have looked on the internet but the code is too cumbersome and since I will be using it on many pages I need something easier like a com.

Here is my code (copied from the net) but it works for one page at a time.

Response.ContentType = "Application/vnd.excel"
Response.AddHeader("Content-Disposition", "attachment; filename=MyIncidentReportFromQTS.xls")
Response.Write("<HTML xmlns:x=" & Chr(34) & "urn:schemas-microsoft-com:office:excel" & Chr(34) & ">")
Response.Write("<HEAD>")
Response.Write("<style>")
Response.Write(" <!--table")
Response.Write(" @page")
Response.Write(" {mso-data-placement:same-cell;}")

Anything in the new framework that has simplified this? Thanks.

I have had luck with just emitting a simple HTML table to the browser stream after specifying the content type.

What do you mean when you talk about "pages"? Do you mean different ASPX pages?

You could create a method in a utility class that does this if you want to share the functionality. The method could accept a data source or a control. You can render just the single control by creating your own instance of an HtmlTextWriter and calling the control's Render method, passing in the writer. Then emit the result to the Response stream and then end the response. That's how I have done it.

What I meant by pages is this. My query might return hundreds of rows and I have my grid limit the table to 25 rows per page and therefore paging. My method specified does not take that into consideration as it only deals with whatever the browser is diaplaying.

Thanks for your response.

Just turn off paging on the control when you emit it for the Excel download, and you'll get all the data.

I already thought of that - what if there are 100's of records?

I am going to turn off paging for the time being till I figure out another way. Thanks for your reply.

You should be fine until you hit 65,535 rows (factoring in a header).
