I am using the Export facilities of the grid straight out of one of your examples and encountering several different problems. The only option that is working correctly is to export to CSV.

(1) When exporting to Excel, my Excel 2010 is opening and the data is loaded from the grid, but after a few seconds, Excel goes into a loop and I have to kill it from Task Manager.

(2) When exporting to a PDF file, the PDF file never displays but I do receive a new window filled with .net errors. (see attached screen capture.

(3) When exporting to CSV, everything works fine and the data is opened in an Excel spreadsheet which operates fine (no problem).

(4) When exporting to Word, Work 2010 starts to open then hangs (never even shows in Task Manager) and I have to click on "Cancel" on the splash screen to get out of Word.

I have included the code (both display and code-behind) below.

The version being used is 2012.3.1016.45; Windows 8 64-bit, VS2012. SQL Server 2008 R2 Standard.

Hi Lynn,

I was not able to replicate your issues. I prepared a small sample based on your code and attached it to this forum post. Could you please give it a try and let me know how is differs from your real setup?

Kostadin,

Thank you for the time spent.

First, your sample did work just fine on my machine. I did change the Northwind database to one already running on my SQL Server because I don't want to install SQL Server Express on here. Also, with Win8/VS2012, there is a new version of SQL Server Express and I really didn't want to get into that.

Anyway...

Second, I have moved the grid in question to another project. I re-tried all of the exporting. When I exported to Excel, it took forever but eventually completed correctly. When I exported to CSV, it actually exported to Excel in just a couple of seconds. When I exported to Word, that, too, took forever. But I waited and it did complete after a couple of minutes.

When I exported to PDF, I received an error. I have attached a screen capture to this forum item for your review.

I should add that the grid is now running on a page that uses a master page for common header/footer/etc.

Thanks!

Lynn

Hello Lynn,

As indicated at the exception you cannot use ".." to exit the root directory. I guess when you are trying to point the path of the image you are exiting the root directory. I suggest you to remove the HyperLink text and then try to export to PDF just to check whether you will receive this exception.

hypercolumn.Text = "<img border=\"0\" alt=\"View\" src=\"../Icons/pencil_16.png\" />";

The code with yellow background is the reason for this behavior.

Kind regards,
