can't drag and drop Ajax Toolkit controls on web pages............

When I try to drag and drop an Ajax Toolkit control onto my web pages I get the following errors.Attempt to read and write protected memory. This is often an indication that other memory is corrupt.When I click the OK button I see one more error message – The operation could not be completed. Invalid FORMATETC structure.I have a Solution with multiple Class Libraries and a Web Site. The AJAX Extensions work such as UpdatePanel, UpdateProgress.My AjaxToolkit.dll is located at the following location on my computer - C:\Program Files\Microsoft ASP.NET\AjaxControlToolkit\Binaries\AjaxControlToolkit.dll I am using Visual Studio 2005 SP1 and Windows Vista Ultimate. I added the AjaxToolkit to the Bin folder and to the Toolbox.I am using AjaxToolkit version 1.0.10618.0. 

When I start a New Website and I use the Ajax Toolkit control website I can drag and drop controls on the Default.aspx without a problem. Even when I delete the existing Web.config file and replace it with the one from my project web site I can still drag and drop controls.

When I add an Ajax Control Toolkit web site to my Solution and cannot drag and drop any of the Ajax Toolkit Controls; I get the above menitoned error messages. As soon as the website is in my Solution the dragging and dropping of Ajax Toolkit controls stops working.

My co-worker runs Windows XP Pro and is using the same Solution he can drag and drop AJAX Toolkit controls into the web pages. What is going on???

Can somebody help me out? Thanks, Newbie

Hi Newbie06,

Your problem is really werid. Since you can Drog and Drop the Ajax controls when using Ajax Control Toolkit template, I think your have installedASP.NET 2.0 AJAX Extensions 1.0 and Ajax Control ToolKit  succeessfully. Based on your description, I'm afraid that we cannot figure out the exact root cause without more of your help. Here are my personal suggestions:

  1. Use "Add Reference" method, it will automaticlly add "AjaxControlToolkit.dll" into your bin directory.
  2. Download an ajax-enabled application from http://www.asp.net/learn/ajax-videos/ , and test it.
  3. Install Visual Studio2005 Service Pack 2(SP2).

Hope these help.  If your problem cannot be resovled, please feel free to let me know with more valuable imformation.Thanks

Best Regards,

Jonathan

Jonathan,

 

I just bought a brand new hard drive and reinstalled everthing - Vista Ultimate, VS2005 with SP1 and Vista upgrade package, AJAX Extension etc. I added the AJAX Toolkit to my Toolbox. Still the same problem I can't drag and drop any of the AJAX Toolkit items into my web pages. I have tried Design and Source view. What kind of information could I give you so that we can troubleshot this issue? There are some neat controls that I would like to use in my project.

 

Thanks,

Patrick

I would LOVE to hear a solution anyone has to this issue.

I have a brand new machine with Vista installed.  I downloaded Visual Web Developer 2008, .Net Framework 3.5, AJAX toolkit, and AJAX futures.

I open a brand new web site project in VWD 2008, try to drag anything from ASP.NET Futures or ASP.NET futures, or AJAX Toolkit and I get the error:

Visual Web Developer 2008 Express Edition
---------------------------
The operation could not be completed. Invalid FORMATETC structure
---------------------------
OK  
---------------------------

We can't be the *only* people out there with this unresolved issue, can we?

Thanks in advance for any advice!

 Hi,

I have EXACTLY the same problem when I try to drag & drop an UserControl!!

It's working in an other solution but not in mine!!

Do you think it could be a problem of public private protected method??

Help Me!

Sorry, I have not been able to find a solution.  I actually decided to uninstall the latest framework and VWD2008 and AJAX futures.  I'm setting them up in a virtual PC and I'll go from there.  At a recent .NET user group presentation, the presenter strongly recommended using VMWare session or virtual PC session for this set up since it is in beta.  Guess I found that out the hard way.

If I find a solution I'll post back.  It would be great if everyone else would do the same.

Good Luck!

I FOUND THE SOLUTION!!!

I had my extended control reference in my WebSiteProject... I thought it was automaticly done but no..

Since I did that everything is fine.

I hope it will help you.. Look into the assemblys and stuff like that

I don't have exactly the same problem as the original poster but I'm also unable to drag the majority of the ASP.NET Ajax Controls onto my page. The only controls that I can drag into design view are Accordion, AccordionPane, MaskedEditValidator, NoBot, Rating, ReorderList, TabContainer and ToolkitScriptManager. Once the controls have been dragged across they do not appear in the design view, although they show in the source. When I attempt to drag any other AJAX control I just get a no entry mouse pointer, no matter where on the page I try to put it.

Annoyingly/thankfully I can successfully use all of the ASP.NET Ajax Controls by manually declaring them in source view, I just think this method takes longer so I'd be interested in a solution. The learning materials that I'm using suggest that there should be an Extender Wizard available from the SmartTag of the relevent controls but I never get a SmartTag (unless the control traditionally gives one such as a DDL or RBL).

I've added a reference to the AJAXControlToolkit.dll in my project and I've tried re-setting the Toolbox to no avail. The sample website works fine but again the controls do not show in design view. Could this be a Visual Studio installation problem/corruption.

Setup:

Windows Vista SP1

Visual Studio 2008 - 9.0.30729.1 SP

.NET 3.5 SP1

All,

 I am not sure how far this will help, but I have similar problem where I was not able to drag & drop any control on my page using "Visual Web Developer". It may sound stupid but in reality if your folder name is "C#" you will not be able to drag drop controls. In may case folder structure was c:\C#\MyCode...I changed it to C:\C-sharp\MyCode....and IT WORKED !!!

 Hope this might help someone.

 Thanks,

Hi all,

I think that the problem is Win Vista. There is no problem with this in XP. But I don't know how to solve it.

I tried these ways:

  1. "Choose items" and selecting the DLL: Invalid Microsoft .Net Module !!!
  2. Adding Reference: Invalid Microsoft .Net Module !!!
  3. Unistalling and re-instaling Visual Web Developer. And 1 and 2. Same problem
  4. Going to XP, Export VWD08 Settings. Copying "Microsoft ASP.Net\AjaxControlToolKit" Folder. Copying the Toolbox files. Importing and pasting everithing in Vista. NOOOO. The toolbox appears as in my XP installation, but I can't drag controls

I can't manage to work with Toolkit for 2.0 nor for 3.5.

In some BLOG I read that recompiling the DLL with Visual Studio solved the problem. BUt of course, I have VWD, not VS. Can this be done with VWD?

I'll have to work on a XP?

Regards
Francisco

EUREKA!!!!!

Rebuilding the project worked!,

I downloaded the last 2.0 source code and rebuilt it with Visual Web Developer 08. Just right-clicked on AjaxControlToolKit.sln, then VWD converted to 9 version and I manually built it.

Hope it helps everyone there.

Can't install Ajax Control Toolkit
I installed Visual Web Developer 2008, and I can't get the Ajax Control Toolkit to show up in my toolbar.  I know i have .net 3.5, since it was installed during the VWD 2008 setup.  And it's my understanding that if i have .net 3.5 installed then I should already be good to go.So I manually installed the Control Toolkit.  I followed the instructions to add the Control Toolkit to the Toolbar.  But still, nothing appears in the toolbar.  Now, when I right-click on the toolbar and choose "Choose Items...", I can confirm that the Control Toolkit IS loaded (check marks appear next to the items). Last year on a different PC I installed VWD 2008 and I had no problems at all.  (So I know I'm able to do it!) Thanks for your help!John Where is your AjaxControlToolkit.dll file?  try to change its location to the location in your VSWD .net assembalies dir, and in Choose Items dialog, browse to a newer copy of dll, it worked for me on 3rd trial or something,  p.s. try to download a copy without sourcecode, just the bin folder, I guess,   I figured it out!  The Toolkit actually was in the toolbar all along, but it was hidden.  I right-clicked on the toolbar and selected "Show All".  All the Toolkit icons magically appeared, BUT they were all dimmed out/disabled.  Thanks to this link: http://geekswithblogs.net/evjen/archive/2007/11/24/117088.aspx I found that i ha...
