Illegal characters in path - ExportToPDF

[Martin Roussel]

Hi, I have a RadGrid defined below. When I click the built-in "Export to PDF" button I get the error listed below:

I found out that it has to do with the ImageURL of the <asp:Image> contained in of the child grid column. If I put a URL link (like "http://somedomain.com/someimage.jpg") it exports correctly.

Is there a way to workaround this or, worse case, handle the export event and remove the image from the export?

Thanks

Hi Martin,

It is hard to say what is causing the problem as the provided information is not enough. Please check the url that you are passing for invalid characters and the ImageHandler as well. For further investigation we will need a small sample where the issue could be observed so we can test it locally.

All the best,

Thanks for the reply. Ive investigated more regarding the URL im passing and the actual value passed is:

ImageHandler.ashx?FileLocation=C:/Images/New%20Folder&FileName=bobby.jpg

It seems to be the "?" that is not accepted.

As you can see, im using a Generic Handler control (that read the files and write them as a response stream), in order to be able to display images stored outside my project folder. In my case, im always passing two parameters to specify the directory and then the file. Is there a cleaner way to do this? I see a lot of people talking about creating IIS virtual directories with aliases and using them like relative paths.

Thanks,

Martin

Hello Martin,

The problem is not in the "?" character. I attached a sample where you could see that in the URL of the image has a "?" character and the image is exported properly. Could you try to reproduce the problem in a small sample or in my project so we can test it locally.

Thanks Kostadin for the reply. Ive inspected your sample and cant find where is the URL with the "?" you're talking about. It looks like your grid contains a RadBinaryImage column which is mapped to a Image data contained in the database (no URL needed).

In my case, there is no image contained in my database and as you can see, im using a GridTemplateColumn containing an asp:Image where the ImageUrl is mapped to a path string from the database.

Or maybe im not looking at the right place?
