Hello,
I'm new to Infragistics, and I'm trying to learn it quickly in order to build a dashboard. I'd found Tom's tutorial videos online and have found them to be extremely helpful in giving me a kickstart.
As a result I've got a prototype built with a webchart which is using a secure image pipe, and data from SQL. In dev (VS 2010), the chart image appears every time, however, the published version seems to be hit or miss. I'll get the chart image sometimes and access denied other times.
I've read through http://ko.infragistics.com/community/forums/t/5477.aspx and some posts on other forums, however, many of them say that this has been resolved in later versions of IG. I'm using Infragistics 13.2 and I can't seem to find any information on this issue referencing later versions such as this one. Actually, I haven't found anything later than 2008/2009.
I'm open to start building the application again from scratch if anyone has a good suggestion for a tutorial using ASP.NET in C#, not VB. I love the 3D charts and guages, and I'm really looking forward to digging deeper into Infragistics and seeing what else I can use in my dashboard.
Thanks in advance!
It turns out that part of the problem is the number of worker processes I have in the app pool. If I limit it to one, then it works every time as in the development environment, however, when I have more than one, it seems to work off and on, seemingly dependent on which worker process is being accessed at the time.
Unfortunately, I can't get away with having just one worker process, and I need to find out why it's not working with more than one. Any suggestions?
Again, thanks in advance!
Hello wynfordit,
Thank you for contacting Infragistics.
I have done some looking into this matter and have some questions concerning this matter. Would you be able to use the IE Dev tools and use the Networking tab/tool? I want to see if you are getting any errors and what the errors are. What service release for v13.2 are you using? Do you get any console errors in addition to the access denied?
Hello Mike,
Thanks for looking into this for us. I believe we have the latest version of Infragistics ASP.NET 2013.2, we had an update run on Jan. 6th. With the various items included, I wasn't sure how to tell the service release, but in the properties of Infragistics2.Web.ApplicationStylingConfigurationv13.2.dll file, I found Product Version 13.2.20132.2028 if that helps.
So far, I've found a correlation between the max number of worker processes on the app pool and the Access Denied error. It seems to work fine in one worker process, but not in others. So, I'm looking into IIS App Pool settings to see if there's something there that might be the cause. I've created an app pool specifically for this app, and I've been testing it with different settings, finding that it seems to work perfectly as long as I'm not using a web garden. I'm not certain how this would effect the ability to support multiple users, but I'm thinking it would limit some functionality to have a single worker process.
Unfortunately, I've been stuck using IE8, and the Dev Tools don't have a Networking Tab, however, I've installed Fiddler2, and I'm familiarizing myself with it, hoping it can give the information we need.
I'll see if I can find a machine with IE9 or newer installed.
Thanks again,

Thank you for the update. Using fiddler to get the network log is good as well. I typically suggestion the browser dev tools as some don’t have fiddler. Once you have the logs please attach them to this thread and I will look closer into them to see what may be causing this issue. When attaching them please make sure they are in a compressed zip file before attaching.
Please let me know if you have any questions concerning this matter.
I've included a zip file containing the fiddler logs. I'm new with Fiddler, but I believe I've saved the logs correctly with the data you'd require. The zip contains two logs, one capturing data for access denied(App Pool set to multiple worker processes), and the other capturing the data from a proper load(App Pool set to one worker process). If you need anything changed to capture in new logs, let me know.
Thanks again for looking into this for us.
Thank you for the update. I have done some looking into this matter and the fiddler logs you have provided. Concerning the designer error this is caused by the designer dll being missing? Did you change the version of the assemblies you use in your project without updating the ones on your computer? Concerning the Access Denied can you provide me with more information concerning this matter? How do you have the UltraWebChart setup? Are you doing anything in the code behind?
A second issue which may be related: I've attached an image of another problem I've been having, 'Error Creating Control' in the designer. The chart works fine when I run the application, but it doesn't properly appear in the designer anymore. It seemed to start randomly, I've been backtracking and reviewing changes I've made, but I can't seem to correct it.
Is it a .dll issue?
