I have noticed that the same WiseJ control appears multiple times in the toolbox.
Last time I opened it items were there twice so I removed the duplicates.
I have just opened a WiseJ app and looked the toolbox and the same control is now there 4 times.
Hope this helps
copy of my answer to the AspNetControl:
the base class AspNetControl is not a UserControl and has the attribute [ToolboxItem(false)].
So derived components to appear in the toolbox must have the attribute [ToolboxItem(true)] and may have to be added to the toolbox.
Hope that helps.
Just in case this is the right place.
How do you get user controls to appear in the toolbar so that they can be added to a design surface such as a Window?
With VWG they were there after the project was compiled.
I have tried on two machines using your Report Viewer example and the control does not appear in the toolbox even after clean and recompilation.
Thanks for your help
Take a look at this.
