Thanks for your replies, Princy and Daniel.

Actually, the first wall that I've hit while playing around with the exports (I attempted to export to csv as it was recommended in one of the various solutions) is the fact that the system cannot seem to process the export at such a large volume.

Here are some sites detailing the kind of issue I'm dealing with (if anyone needs a reference):
http://forums.asp.net/p/1281278/2449394.aspx
http://discuss.fogcreek.com/dotnetquestions/default.asp?cmd=show&ixPost=4787

In regards to office 2007, unfortunately I can't force my users to upgrade as the current standard is 2003.

With splitting the results, would that mean I would have to develop a function to do it? Or is there a way, using Rad tools, to bind a grid > export to a sheet, create a new sheet within the same work book > bind grid > export etc or would I have to create a new worksheet at each export?

Hi,

I'm not sure why but I'm getting OutOfMemoryException when I try to export records. But it is not as large as 65k. The actual count is 32787. So I'm not sure why this is happening.

I hope someone has a solution as I'm confused about what to do here. It works fine if I split them as 1000 records but the users do not want to do it through multiple excel files.

Hello Jaroslav,

I believe there is no way to export such enormous amount of data.

Please try the following: Set IgnorePaging to false to display all the 50000 items in 30 columns in your browser. Then run the task manager and let me know how much memory is occupied by its process.

For testing purposes, I tried this with 50,000 items and just 3 columns - the result was 470MB footprint. Please notice, that I'm the only user exporting at this time - imagine what will happen if there are 5 users, each of them exporting 50000 items in 30 columns simultaneously.

I hope my explanation was helpful.

Hello Kurt,

RadGrid is capable to export limited quantities of data. Should you need to export large datasources it would be better to use a separate exporting component, reporting control, or your own exporting library (you could use NPOI to generate the file) that fetches the data directly from the data source.

Even if we theoretically improve the speed and memory footprint three times (just an example) you will get the same exception if you have three users that export the same data in the same time. This is why we do not recommend to use RadGrid in such scenarios.

Hi,

I implemented the paging technique and allowed them to download the report partially. They tried it until now but now the database has grown too big to do it partially. They are asking me for a solution or else they will take the project to someone else.

The excel sheet is about 60MB when generated. And Microsoft Excel 2007 comes with 1,048,576 rows by 16,384 columns. So why is it still generating in the old 2003 version? Why can't we generate it in xlsx format? That should fix this problem shouldn't it?

Also, someone told me to try serliazing the object before putting it in the stream to convert it. I'm wondering if it is being serialized here internally before convert.

I would really appreciate it if you can get back to me ASAP. Look forward to your response.

Kind Regards,
JB

Hello Telerik Team,

I am not sure exporting issue is constrained to Excel 2003 or 2007.
I am trying to export out a huge amount of data to a PDF file from the Rad Grid.
But i end up with the

Exception of type 'System.OutOfMemoryException' was thrown.

My Server has about 4 GB of available RAM, the w3wp.exe process only consumes 1.4 Gb (1,040,708 K) when i got this error.

Hence I notice that, although the server has a lot more memory to consume, the export crashes after consuming about 1.4 GB.
i prioritised w3wp.exe instance to use Real Time Memory through Task Manager, but that doesn't help either.

What can I do to for this.
I am trying to export about 500K rows with 5 columns of data. What would you suggest I do for this ?

Hi Kalai,

RadGrid provides various excel formats:
https://demos.telerik.com/aspnet-ajax/grid/examples/functionality/exporting/excel-export/defaultcs.aspx
https://demos.telerik.com/aspnet-ajax/grid/examples/functionality/exporting/pdf-export/defaultcs.aspx

But I'm afraid it is not suitable for exporting large amount of data:
http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/functionality/exporting/overview#export-large-amount-of-data
http://www.telerik.com/forums/system-outofmemory-exception-while-exporting-telerik-grid-data#6viUZtAzT0SLWwX3EfTauQ

If you want to reduce the exporting time, the only viable option would be to export only a portion of the items by removing or disabling the IgnorePaging property.

You can also check RadSpreadStreamProcessing for building the data in the exported file manually, but please bear in mind this would be a custom endeavor and beyond our support scope:
https://demos.telerik.com/aspnet-ajax/spreadstreamprocessing/large-document-export/defaultcs.aspx
https://docs.telerik.com/devtools/aspnet-ajax/controls/spreadstreamprocessing/overview.html

I really want to to offer you something feasiable, but I'm afraid it won't be possible in this case. The count of records is too much and this kind of massive exporting is just not supported with RadGrid.

Eyup

Hi Sajid,

I understand that you're facing an issue while downloading more than 50,000 records into Excel. However, as mentioned earlier, this forum is specifically for RadGrid in ASP.NET AJAX, while your issue relates to Telerik UI for ASP.NET MVC Grid which is a different component.

If you want to export large amount of data with RadGrid follow the instructions in this KB article: Export large amount of data to PDF, XLSX and CSV using the Telerik Document Processing libraries.
For exporting large data with the Kendo UI Grid check this article: Export Grid to Excel with the RadSpreadStreamProcessing Library.
