Visual Studio toolbox

Oct 27, 2008 at 9:58 AM
After installing the NHS CUI toolkit and building the source and working through the sample I wanted to try using the controls in a new C# web application.
I looked in the toolbox and found no tools.
Did I do something wrong in the installation?
Where do I import the controls from?

Managed to download the latest version and went through the controls import and managed part of it.

Got the following errors
There was an error loading types from assembly Microsoft.Cui.Controls.dll
Could not load file or assembly 'System.Windows, Version=, Culture=neutral, PublicKeyToken=7cec85d7bea7798e' or one of its dependencies.
The system cannot find the file specified.


There are no components in Microsoft.Cui.WPFControls.dll that can be placed on the toolbox.

Hi Major

Regarding the error you saw, could you let us know what OS and Visual Studio version number you are using please?

As far as the toolbox functionality is concerned, we have found that most of our customers are reusing the controls as source, rather than binaries, so the toolbox integration isn't adding a great deal of value. As a result, for some of the newer, WPF controls, we are shipping them without toolbox integration. We welcome any feedback in this area - if this causes big issues for people we will consider adding toolbox integration in a later release.

Hi Major

I think the error you are seeing could be a result of not having Silverlight installed. The best approach would be to install the SDK, rather than just the runtime. The best place to start is

As far as toolbox functionality is concerned, you can of course manually add the controls to the toolbox. However, obtaining a fully-functional control by simply dragging-and-dropping from the toolbox onto the design surface is not one of our core scenarios. So there will still be some code to write to bind the control to your data sources and apply the relevant visual styles.

Hi Major

Apologies for the long delay in responding.

Do you have access to another machine that you can try this out on to see if the error is reproducible?

Hi Major,
I just follwed these instructions and verified for 1.2 release on VS 2008. Did you do this?
