Cannot get Picture Toolbox items to appear in VS 2005?

[Frank Hileman]

If you add to the Toolbox in Visual Studio 2005 Picture-derived classes that are located in an external assembly, you should find that the Toolbox items can be used fine as sub-Pictures, but they do not appear, or are disabled, when using the Forms designer.

To fix this, add the following attribute above your Picture derived class (C# syntax):

Code: Select all

[ToolboxItemFilter(Picture.ToolboxFilter, ToolboxItemFilterType.Allow)]

VB syntax:

Code: Select all

<ToolboxItemFilter(Picture.ToolboxFilter, ToolboxItemFilterType.Allow)> _

After rebuilding, reset the toolbox, and add the assembly and Picture items again. This time they should be usable as top-level Pictures in a Canvas, as well as sub-Pictures in other Pictures.

You can also change the Toolbox bitmap for a Picture if you want to have a fancy icon.

I am getting the same problem with disabled toolbox items in Visual Studio 2003. How do I remedy it with .Net Framework 1.1, since the constructor parameters for the ToolboxItemFilter are different (it takes a string and a ToolboxItemFilterType)?

Ignore me - I'm being stupid. Picture.ToolboxFilter is a string!!!
