I have deployed an ASP.NET 2.0 application that is using neadvantage 7.1 for ASP.NET. Sometimes randomly, when a page that contains webdatechooser control is loaded, the following error occurs:
Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:Arial; mso-bidi-theme-font:minor-bidi;}

The user can go further unless the IIS server is restarted. As you can see, all the method call that are involved in the error are from Infragistics and .net framework. Any clue on how to solve the problem?
Note: Sometimes the error appears for other infragistics control such as ultrawebgrid etc.
I've seen a very similar exception reported to Developer Support recently by another customer. It seems to affect a number of different controls (the other customer is using WebMenu, WebChart, and WebTab), and seems to require an IIS restart once it occurs. We're still looking into the matter ourselves with all due thoroughness.
If you haven't already done so, I suggest that you submit a support request. I recognize that this may be difficult to dependably reproduce in a sample project, but if you're able to create one, it would likely help us to resolve this issue much more quickly. Even if you can't reproduce the behavior, any additional information you can provide as to what seems to be the cause will be helpful.
has there been any resolution do this issue?
A similar issue was fixed in the most recently released hot fix for NetAdvantage Web Client (ASP.NET). You can download the hot fix from the My Keys and Downloads page of our website. You may want to test this to see if it addresses your issue.
If the exception continues to occur, then please submit a support request so that we can investigate further. (EDIT: I just noticed in your earlier post that you've already done this.) As I mentioned earlier, providing a sample that reproduces this behavior is the best thing you can provide to assist us in identifying and resolving the issue, particularly if you're still seeing it occur despite having the most recent hot fix installed.
Hello - just had the same issue on dev box. Was adding some controls to new pages in a sub-folder with in a site. I upgraded last week to
8.3.20083.2115 hot fix version.
Restarting IIS seems to have fixed it for now. Will post if I continue to see this. Exception below:

I’ve opened a trouble ticket for this one, as it seems to be a reoccurring issue for me.
Any update on this? Following an upgrade from 2008 vol. 1 to 2009 vol. 1 (9.1.20091.2087), we began experiencing this issue at random times and only on one development server. IIS reset always seems to get rid of the error (until next time). Here is a stack trace:
Stack TraceObject reference not set to an instance of an object.Object reference not set to an instance of an object.

Thanks
I'm experiencing the same issue and just submitted a ticket. Wow I hope they fix this soon I've had it happen in two different applications now.
Have you resolve this problem ?
I have the same probleme with WebDateChooser et WebTextEdit (Infragistics 2009 Volume 2)
I submit a support request but I did not get response yet.
FYI ... see the thread addressing this in 2009.2. I was having this issue in 2009.1 and it continues in 2009.2.

Rob,

It's not yet certain whether the behavior you've described is caused by the development issue I mentioned before.
I'm having your case assigned now. To be fair, this will take us time to verify what's happening in your situation. Thank you for your patience.
Hi Rob,
I haven't seen this issue on our production server since I added the WebDateChooser dll to the GAC. Mind you it was already in the GAC, but since I was getting this error and on occasion one that says:
System.IO.FileNotFoundException: Could not load file or assembly 'Infragistics2.WebUI.WebDateChooser.v8.3' or one of its dependencies. The system cannot find the file specified.File name: 'Infragistics2.WebUI.WebDateChooser.v8.3' at System.Reflection.Assembly._nLoad(AssemblyName fileName, Str
I decided to add a fresh copy to the GAC in case it got corrupted somehow.
I used the DLL from the "C:\Program Files\Infragistics\NetAdvantage for .NET 2008 Vol. 3 CLR 2.0\ASP.NET\Bin" and not from APTCA or Signed folders.
Running .net 2.0 on win2000 advanced server.
Hope this helps
