MS Visual Studio: The operation could not be completed. Invalid FORMATETC structure.

Asked By ScottGarcia 10 points N/A Posted on - 08/15/2011

There is a Microsoft Visual Studio 2008 project on the website, which I am working on. There is a page open with split-view and when an infragistics web control is dragged to the htmlz, a dialog box pop’s up.

How do I fix this? What happened to the version, which was working fine on my Windows Vista machine?

Can anyone judge what could have caused this error message?

Hello Scot,

To fix this error, first you must try the simplest method and check what happens. Simply, right click the Toolbox and choose the menu of Reset Toolbox. By doing that,  it resets the control references and assembly has been reset and you will get rid of this error.

Or you can perform another task and do it manually. You just have to unload the current project and upgrade this project or any other previous  ones, on which you are working. Then go to the folder of WebApp > Bin and check the, system.web.extensions.dll and fix it.

For a more detailed solution you can visit this website.  

I am also attaching the image for your ease, so you can see where to go.

I think this will be helpful for you. 

Thanks
