SharedFile feature prevents uploads at a certain number of pdf files

  • MojoPortal Version 2.3.6.2
  • MSSQLOperating System Microsoft Windows NT 6.0.6002 Service Pack 2
  • ASP.NET Info v2.0.50727 Running in Full Trust
  • SQL Server 2008 R2

the following page errors out when attempting to upload additional pdfs via the SharedFiles.

url: http://yc-acc.yccd.edu/yc-resources.aspx

error:2012-08-15 16:07:17,237 ERROR mojoPortal.Web.mojoBasePage - 10.10.16.68-en-US - /yc-resources.aspx
System.InvalidOperationException: Operation is not valid due to the current state of the object.

as per forums -- upped value here in <add key="aspnet:MaxHttpCollectionKeys" value="3000"/> -- still errors out. Have we reached the practical limit of this feature on this page?  Should we keep upping the value= number?

Would upgrading to the current version fix this -- or should we break this page into one page per SharedFiles feature - thus limiting the number of files on each page?

Re: SharedFile feature prevents uploads at a certain number of pdf files

You could keep increasing that number, or it should also help if you group the files so there are not too many per folder, and not too many top level folders. The more items databound to the grid at once will increase the number of form elements and viewstate.

Also you can remove this attribute from the <pages element in Web.config:

maxPageStateFieldLength="500"

removing that will set the viewstate size to the default which is much larger so that there will be fewer separate hidden elements used for viewstate. ie it doesn't reduce the amount of viewstate but it reduces the number of separate viewstate elements.

The only reason we set it low is because in some older phone browsers it would not load hidden fields if they are very large.

Hope that helps,

Joe
