VS2010: Why do my custom Toolbox tabs and contained controls keep fading?

Question

This is how I expected the toolbar to work:

Let's say I add a custom tab to a toolbar called "Ajaxtoolkit". To add controls to a new tab, right-click and select "Choose Items" and browse to the Ajaxtoolkit.dll file, which refers to a specific version number.

I would expect that when I save and open the solution again, the custom Ajax Toolkit tab will still be in my toolbar and that it will contain the same controls that were the last time, the controls that were in the DLL, that I when the controls were added.

If I created a completely new web application, I (probably) did not expect to see the same custom Ajax Toolkit tab. However, I could follow the same steps as above and add the “Ajax Toolkit” tab and, perhaps, this time select a DIFFERENT version of the capture, and the state of the toolbox will be saved with each solution file.

Another possibility for the original Ajaxtoolkit will remain when creating the second web solution, and perhaps if I want to combine the toolkit versions on different sites in my solution, I should start calling my custom toolkit tabs with specific version names such as "Ajaxtoolkit 4.0 " etc.

... But instead, the Ajaxtoolkit tab disappears when I close VS2010 and open it again.

Why? Is this a desired behavior or a mistake?

Answer 1

You know, VS2010 is a fully customizable IDE, perhaps these features conflict with the configuration of your toolkit.
