For clearing the toolbox give this a try:

Close all instances of Microsoft Visual Studio.2. Delete all cached toolbox items by removing all files beginning with "toolbox" from %LocalAppData%\Microsoft\VisualStudio\9.0.

On Microsoft Windows XP, %LocalAppData% is Documents and Settings\UserName\Local Settings\Application Data.
On Microsoft Windows Vista, %LocalAppData% is Users\UserName\AppData\Local.

Btw, I recommend going to the RTM version of SL if you haven't, and there's an even newer version of the DataGrid:

One thing you can try is right clicking the empty space inside the toolbox and select Reset toolbox

I tend to do all of my GUI work in Expressions Blend and only code in Visual Studio. I cannot get the same control of looks and ease of use, not to mention the oh so long time it takes the cider to interprit the XAML.

Hi,

I have the same problem. I can't drag and drop from the toolbox to the XAML code.

MessageBox "The operation could be completed"

Has anyone a solution?

Best regards

Jochen

This isn't a very high priority to me because I can do everything by hand.

To test your idea I just added a new Silverlight Application project to my solution:

1) Right click "Solution \ Add \ New Project"
2) Select "Silverlight Application" and press OK.
3) Uncheck "Add Test page..." and press OK.
4) Drag a "Button" from the toolbox into the "Grid" and get the error.

I also created a new solution:

A) Open VS 2008 standard
B) Select "File \ New \ Project" and "ASP.NET Web Application"
C) Follow steps 1 through 4 above and get the error.

Then I created a new solution:

A) Open VS 2008 standard
B) Select "File \ New \ Project" and "Silverlight Application"
C) Select "Dynamically generate an HTML test page..."
D) Drag a "Button" from the toolbox into the "Grid" and get the error.

This leads me to think that something needs to be re-installed.

I tried your Xaml. It works fine. I can Drag and Drop any control in it. Have you tried to add a UserControl or even start a new Silverlight project and see if you still have the same problem?

The following Button works fine. If you try to drag a button from the Toolbox above or below it you get the error. (And this happens in any xaml in any project in my solution. It happens within a Canvas or StackPanel or any general xaml anywhere in my Solution that I have tried so far -- 5 or 6 different xaml files so far.)

I usually hand code my xaml so it might have been a while since I dragged and dropped something. So It might be hard to tell when this started.

Thanks

</Canvas>

</UserControl>

I thought you had the same problem as the original poster. If you have been running beta2 for a while, then my post does not apply. Where do you want to drop the control? You can only drop it to the Xaml area, not the designer area.

Opps. Maybe my memory is bad. I have been using Beta 2 for quite a while without any problems. This just started. Although I'll try your procedure and see what happens (everything compiles fine and executes).

I never used Beta 1. I started with Beta 2.

If you just convert your beta1 project to beta2. You need to remove System.Windows.dll, System.Windows.Controls.dll from References. Then add System.Windows.dll, System.Windows.Controls.Data.dll, System.Windows.Controls.Extended.dll to the References. Before you hit compile, exit VS (otherwise, you might get a lot of error which does not make any sense). Then re-open VS to compile your project. Now you should be able to get some meaningful compiling errors which you have to fix by hand.

You also need to check your Xaml files. Because a lot of breaking changes in beta2, some property name changed you need to fix them by hand. The compiler should indicate which line is invalid.

I am having this problem with my whole solution.

In any project that I try to drop a button from the toolbox to any xaml I get this error (I tried 4 out of 10 projects).

I can hand code the button in xaml ok. But I can't drag and drop from the toolbox.

I finally got this working by opening a new project and adding a datagrid - and then copying everything over to the new project. There was probably some odd reference in there somewhere - but regardless making a new project fixed it.
