   I was having problems w/getting the Prometheus controls to appear in the VS2008 toolbox (even after running the toolbox installer and manually trying to add them). I finally realized that the controls won't appear unless I set the targeting of the project to .NET 3.5. The docs seem to imply all of this should still work even if I'm targeting the 2.0 framework. I tried adding the assembly from the bin directory (instead of bin35) w/o much luck - the controls still wouldn't appear.
  
  Is this supposed to work or is there something else I need to try?
  
  Thanks,

  Hi,
  
  Visual Studio 2008 ships with ASP.NET Ajax version 3.5. If you want to use the Prometheus controls in a 2.0 framework web site, you need to install ASP.NET Ajax 1.0. After you install the old version of the Ajax extensions you should be able to add the controls from the bin folder (compiled for 2.0) in the Visual Studio 2008 toolbox and use them in 2.0 applications. The controls in the bin35 folder are compiled against ASP.NET 3.5 and cannot be used in 2.0 web sites.
  
  Best wishes,
  Lini

   I had the 1.x MS Ajax libraries installed before installing Prometheus. I re-downloaded the VS2008 templates and installed them. My project references the System.Web.Extensions v.1.0.61025.0 version. The controls still don't appear in the toolbox. I tried adding the controls (selecting the Telerik.Web.UI.dll file in the bin folder), but they still didn't appear.
  
  I did some more digging and it seems to be related to the fact that I am still running VS 2008 B2. There are steps in the comment section related to users that can't see Ajax 1.x stuff in the toolbox after adding it (and how to fix it).

  I followed the steps, started up VS and in the toolbox did a right-click show all. Then I removed the Prometheus controls tab and exited VS again. I ran the app to register the Prometheus controls in VS again, then started up VS. Now the controls appear.

  This happens to me as well using the RTM version of the VS 2008 Professional, and the workaround works for me as well.
  
  Please note that I am targeting ASP.NET 2.0 and have version 2.0 of the Prom controls installed on my machine. I know nothing about the 3.5 version of the Prom controls.
  
  Instead of letting people having the same problem hunt for solution, I will post all the required steps here:
  

  1. open VS 2008, in the toolbox, right click and select "Show All", and "Delete" the Prom tab
  2. Close VS 2008
  3. Go to C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.5\
  4. Make a backup copy of these two assemblies on your hard drive
     - System.Web.Extensions.dll
     - System.Web.Extensions.Design.dll
  5. Delete these assemblies from the C:\Program Files\....\v3.5\ folder.
  6. Click on the 'Register RadControls 'Prometheus' for ASPNET Q3 2007 items in the Visual Studio toolbox' short cut found in the Telerik section in start menu
  7. It should work from now on

  I just purchased and installed Prometheus and was experiencing the same issues.  Like some of you said - it was the fact that I was targeting v2.0.  I simply created a new tab on my toolbox and pointed it to the bin file (not bin35 obviously): Telerik.Web.UI.dll.  Works great now!

  I was having problems with the VS2008 toolbox and nothing I tried worked. I then did a general search via Google and found the following thread:
  
  http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2670124&SiteID=1
  
  If you scroll to the bottom of the thread you will read about a bizarre situation in which if you have a Microsoft Wireless keyboard and you unplug it then all your greyed out Telerik controls will start working!
  
  It worked for me. I unplugged the USB lead and all the controls became available. Plugged the lead back in and I can now select and use them. Early days yet as I don't know if they will be greyed out when I restart the PC.

  OK, the Microsoft Wireless keyboard. Unbelievable !! Yes, this fix works !! I was having some pain tring to make this work, this post should be at the TOP what to do list when using VS 2008 and Telerik.
  
  I unplugged, all controls visible, plugged back in, all controls visible and useable.
  
  What a catch !! You get my award for 2008 !! Thanks for posting this.

  I experienced this problem as well -- although I was using RadControls Q3 SP1 (not the Prometheus controls).

  I've given up on the VS2008 for the time being, not due to the Telerik controls. The web designer seems to be terrible. Apart from being slow and crashing, it doesn't seem able to cope with HTML tables very well.
  
  Trying to select a column on a table displays the properties for the table and clicking on a cell to place the cursor in it causes the whole page to be selected, displaying the properties of the first control on the page and scrolling up to the top if there is someting like a PageView control on it.
  
  It took me over two hours today to move a few controls around and when I eventually gave up and went back to VS2005 it took 15 minutes!
  
  Moving controls from one place to another on a page is very slow and placement is inaccurate. It seems to put them into the nearest <div> tag even though you placed it outside.
  
  I will have another go when I've got more time to play around with it!

  Ken -- Thanks!!!
  I have a Microsoft wireless mouse and I'v experienced the same problem.
  Thanks to your advice the RadControls got enabled after unplugging the mouse. What a wierd thing. The Telerik should  do something about it.

  BTW, I've been working with the troubleshooting guys at Microsoft on this issue.  It's actually not a Telerik issue.  It's a Visual Studio issue as this happens with other third-party controls as well...

  Anyone figure this out yet?  I have not been able to get the controls to appear in my toolbox.  I'm building a 2.0 app in VS2008.

  Does unplugging and replugging in your mouse / keyboard while VS2008 is running add the controls to the toolbox?
  
  If so, that is the solution until Microsoft delivers a fix.

  I tried that, but unfortunately that didn't do the trick.

  Sorry that didn't work for you Dave, it's a pretty frustrating one.
  
  Microsoft has me running Spy++ to capture messages sent to Visual Studio 2008.  They seem to think that the problem is due to the fact that VS populates the toolbox during the "idle" event and that in some hardware configurations it receives too many messages from another device to ever become idle.

  This is a 4-year-old thread, but the issue is still the same with VS 2010 apparently.  After googling for some help I found this thread, so I tried unplugging my wireless mouse before adding the controls, and it worked!  With the mouse plugged in, the controls were never added to the Toolbox even though I restarted Visual Studio.
