  I get the same problem. None of my controls work. If I drag any telerik control over to a page I get the following message "Attempted to read or write to protected memory. This is an often indication that memory is corrupt.". This message is followed by this message "The operation could not be completed. Invalid FORMATETC structure.". This could be an empty page, a content page or a user control. Doesn’t matter. I even tried to reinstall the rad controls, and didn’t make a difference. All the other asp.net controls work just fine. Can drag any non-telerik control over to page without any errors. This is a problem!!!!!!! Please HELP.
  
  NOTE: I am using source control TortoiseSVN. Looking at the directory and the contents, all directories and files are read-only. Why isn’t VS having the same problem writing to these files??? What is it about the RAD controls that are causing this problem?
  
  NOTE2: The RAD controls work when source control is not being used.  This doesnt do me any good or the rest of the company.

  Hello Charles,
  
  In general, we do not believe this error could be directly related to our controls. Therefore, I suggest you search asp.net forums for similar problems and possible solutions.

  I am getting this error in the Q1 2007 release. I'm using Vista.
  
  It might be nice if telerik could research this error and post a solution for it rather than punting and pointing to the asp.net forum. It very well may not be an issue with the telerik controls but this the first place people are going to to when this error is received so it would be nice of the solution could be found here as well.

  Rh,
  
     This is an often observed, rarely answered problem in VS2005, and it's not relegated to the Telerik controls.  There are several articles you can google for describing similar errors, but there are different resolutions, and even then, they may not work for you.
  
     I've been told that VS2005 SP1 relieves this problem (but NEVER told that it eliminates it!), but since I haven't had the problem since the initial release of VS2005, I really couldn't tell you for sure.
  
     Finally, watch out for Vista, even if you have administrative rights, you don't always have complete administrative rights (as wierd as that sounds).  So make sure you are running with elevated permissions, or turn off the UAC in Windows Vista.

  Hello,
  
  I have had this problem and gotten rid of it by exiting VS2005, deleting the dll from the project's bin folder of the control I am having a problem with and restarting VS2005.
  
  I have also had similar problems dragging a new version into a project that has an older version reference.
  
  Just a couple ideas.
  
  
  Regards,
  John

  I upgraded to a new laptop with vista and put VS2K3 SP1 w/Vista patch, branched my code, and upgraded from the telerik Q4 2006 controls to the Q1 2007 controls all in one fell swoop. I guess that is just begging for an issue to occur. :)
  
  After I cleaned my solution, deleted all the existing references, and closed VS and reopened it worked.

  I was having the same issue and the reply which said to delete the Rad dll's from the bin folder worked great.  I am now up and running and the issue is resolved.

• Brian

  Posted on Sep 8, 2007 (permalink)

  I was just having this same error (in VS2008 B2) and discovered I had moved the place I originally added the references from. I simply moved the folder back to the original location and it fixed that issue.
  
  I'm sure this is the same as deleting the references and resetting them, but this worked for me too...
  
  just FYI...

  I got the following error in VS 2008, WinXP, RadControls for ASP.NET Q1 2008:
  
  The operation could not be completed. Invalid FORMATETC structure
  
  I tried re-installing the controls several times, but it did not work.
  Finally, I manually added references to all the Rad controls to the BIN folder. Then, I tried to drag the components on the web form, and it worked!!

  I just had this issue a few minutes ago and I have had this issue with other controls. Just close the project, deleted the .dlls in the bin, deleted the .sln and .suo, you will need to show hidden files for the .suo, and deleted any references to the telerik controls in the web.config.  I then opened the project using the .csproject file and you should be able to add the controls.  I am using Visual Studio 2008 but had also done this with 2005.

  Same error.  Did what Thomas said, minus the deleting dlls part, and it's now fixed.  Q2 2008.

  Using the Q2 2008 controls and this happens randomly.  Telerik claims this is nothing to do with them which sounds suspicion as I have dev express and the built in controls never have this problem.
  
  When I try to drag a control onto a web form, I get "The operation could not be completed.  Invalid FORMATETC structure."
  
  Not pointing fingers just yet but not a very good response to pass the buck instead of getting to the root of the problem.
  
  The only fix I have is to delete the telerik tool bar, create a new one and add a reference to the dll.  However, this is getting highly annoying.

  I just got the exact same error after upgrading to the latest RadControls.  The error is clearly directly related to the installation of the controls.

  I was running into the same problem.  I came across the following post that helped me resolve the problem:
  
  http://www.c-sharpcorner.com/UploadFile/mahesh/IFSError09112008132606PM/IFSError.aspx
  
  Basically what I did was to reset the toolbar in Visual Studio and then re-add the Telerik controls.

  Hi Guys,
  
  Not sure if this will fix your issue or not, we had the same probelm using .Net 3.5 and VS 2008.  It turns out we added the dlls in the standard bin directory instead of adding them from the bin35 directory.  It sorted it for us.
  
  Cheers,

  I have to say, I think it is telerik.
  
  I have been with the 3.5 version since March 2008 and every single time I have to upgrade my dll I run into this freaking problem.
  
  Just upgraded again and usually I can find a way to get it to work.
  
  But I am not having such luck with the 11/5 upgrade version.  I am getting this stupid error.
  
  It takes away my intellisense as well.  So unless I have all of the documentation remembered this control has become unusuable to me.
  
  Telerik should research the problem.  After all part of Telerik's "job" is to integrate with Visual Studio.  They are a control that is specifically written for for the VS environment.  Specifically to work with intellisense.  Specifically designed for .net applications.

  Hi Angela,
  
  Unfortunately we are still not able to designate the exact reason for this VS design-time issue. You will probably agree with me that this problem is related both to our server controls and the .NET framework itself.
  
  Can you please check whether restarting your VS environment makes a difference? You may also check whether starting a new web site from scratch or clearing your VS cache alleviates the abnormality.
  
  Kind regards,

  Hi Sebastian,
  
  Thank you for your reply.
  
  The solution you offered did not work.  I have virtually tried everything.  Before if I had this problem I would still be able to work with intellisense.
  
  Now I can't work.  Intellisense is turned off for the aspx page.
  
  What I have tried (I am using Web Application Project not a website)
  1) Uninstalled Previous Version
  2) Installed new version
  3) Deleted my dll in my bin directory and replaced it wil the new installed version
  4) Removed the Reference and Added it again.
  5) Reset Toolbox
  6) Add new RadControl Tab by hand
  7) Rebuilt the Web Application Project - Meaning new project from scratch and readded all my files.
  8) During all this loading and unloading VS 2008 at various points.
  
  This is just not good....
  
  For me it is Telerik problem.  Yes you might have trouble with VS but overall it is Telerik's responsibility to their customers to provide something that works when upgrading to newer versions.
  
  It is at the very basic level of functionality that is needed from the control.  It is not like having browser compatibility problems with a control.  It is to the point where it stops developers from developing anything just to get their own environment to work.
  
  Any other suggestions I am open to trying.
  
  Thank you for chiming in and giving your thoughts,
  
  Angela

  Posted on Jul 6, 2009 (permalink)

  I've encountered this problem and only in relation to Telerik controls after installation of the latest version.
  I have yet to find a single solution that works 100%.
  

• Daniel Daniel

  Posted on Jul 6, 2009 (permalink)

  Hello Doug,
  
  Sorry to hear about this problem. So far the best option that helps (in most of the cases) to resolve the error is to delete the controls from your BIN folder, restart Visual Studio and then add them again. As someone already explained below, there isn't 100% working solution because it seems that the reasons that are causing the problem are probably more than one.

  i recently downloaded the latest msi install and now i am unable to use any rad controls period. Used to be you dragged a rad control on the page and then hit the smart tag to add the web config settings - i don't get that at all - what has happened here? I've uninstalled older versions, reinstalled latest, went back one version, add reference manually, putt dll's from telerik samples into my new web site - nothing works.
  
  how am i supposed to explain this on my time sheet? 8hrs of nothing! what to do?
  
  when i click the convert to telerik web site web config shows this - where is the versioning?

  Hi Jeff,
  
  As long as the website uses a bin-deployed assembly, it does not need version information in the web.config file, that's why the Visual Studio Extensions do not add that. You could determine the version of the Telerik.Web.UI assembly by using the WebSite Property Pages (right-click on the website in VS Solution Explorer and choose "Property Pages...") - the References tab displays the version of the assembly. The other option is to start a Windows Explorer, navigate to the website bin and check the properties of the Telerik.Web.UI.dll file.
  
  Still you are right - it would be useful if the Upgrade/Configure dialogs contain information regarding the version of the Telerik.Web.UI assembly currently used by the website. We are working on that.
  
  Regarding the drag-and-drop of a RadControl and Smart Tag usage - this is still a valid approach. The purpose of the Visual Studio Extensions is to eliminate the need to use the Smart Tag - you just get the web.config pre-configured.
  
  Let me know if I am missing something.

  This error just started happening today.  Nothing in my environment has changed.  I added a new user control to my project and attempted to add a Rad Rotator to the page when this error occurred.  Using source safe, I restored my project to before adding the user control, but the issue persists.  This worked last week and no settings have changed, I have tried most of the above suggestions; all those from Telerik employees including the latest suggestion from Daniel on Jul 6, and some from other users without success.  I have tried creating a new project and adding the controls but got the same error.  Has a fix been locked down for this yet?  I am running Server 2003 w/ VS2008.

  
  

  Thanks,

  Hi John,
  
  I'm afraid we are out of suggestions regarding this one.
  
  I'll be more than glad to help finding the core of the problem on your side (an possibly help other customers too).
  
  Can you check the list of the Windows Updates related to the Visual Studio IDE, which got installed on your machine lately? Can you post them here?
  Additionally, did you make any changes to the system (installing some third party additions to the Visual Studio IDE, or changing the Visual Studio components)?
  
  Looking forward to your reply,

  I was using a fresh install of VS2008.  The install included .NET 3.5 SP1.  I also have ReSharper v4.5 installed in my dev environment.  ReSharper came before Telerik.  I installed the trial version of telerik controls which I used for 2ish weeks util purchasing the license last week.  I never had any issues with the trial version.  I had not installed any updates for VS2008 until I saw your reply.  Just now I installed all the latest fixes, those related to my dev environment are below.

  Microsoft .NET Framework 3.5 SP1 (KB963707), (KB958484), (KB953595)

  Microsoft Visual Studio Team System 2008 Team Suite (KB971091), (KB973674), (KB952241)
  
  After installing these updates and restarting my machine, the error still persists.  I also again tried removing the references and re-adding them which also did not fix the problem.
  
  Thank you for your help!

  Hi John,
  
  I searched some more about this error. I found several suggestions, but I don't think any of them could be related to the problem you experience - they are related to existing projects while you've had the error with a blank project...
  Just in case, here are two interesting articles (there are interesting comments there too):
  http://bchavez.bitarmory.com/archive/2008/01/23/invalid-formatetc-structure.aspx
  http://codeforfuture.com/2009/02/04/solution-invalid-formatetc-structure/
  
  Can you try resetting the toolbox? This is one of the suggestions Jayvardhan Patil mentioned and it could help...
  
  Another thing you could try is deleting the contents of the Temporary ASP.NET Files folder.
  
  Let me know if any of these helps.

  Hello,

  I know that this thread is one year old, but there are odds that some people might run into this issue (just as I did after upgrading to 2010 Q2).

  Make sure that the control you're dragging from the toolbar has the most recent version (by right clicking on the toolbar, selecting "Choose items.." and ensuring that all entries referring to the "Telerik.Web.UI" assembly point to the latest version of the DLL). In my case something went wrong after updating and the VS toolbar had dangling entries which caused the dreaded FORMATETC error.

  I hope that will help.

  Cheers,

  Łukasz

  I just recently got this error when after upgrading to version 2010.3.1215.35 so there is something more to the problem. I could not drag and drop a RAD control onto the page without getting the FORMATETC error message. If I added the control by typing in the code, intellisense would not recognize the telerik tag.
  
  I tested to see if I got the problem with an asp control and the FORMATETC error message never happened, and the control work fine.
  
   Finally after reading other posts about deleting the Telerik.Web.UI.dll from the bin folder, found something that worked for me. The reference in my project for Telerik.Web.UI had the Copy Local property set to false. I set it to true, compiled the project, and now I had no problems dragging and dropping a RAD control onto the page.
