I have a 3 level inheritance.

class Level1 : System.Windows.Forms {}
class Level2: Level1{}
class Level3 : Level2 {}

in the load event from Level1 I call a overidable method, that in Level2 is override and in this I make some initialization for information on the form, DataBinding and one SqlDataAdapter, but when I whant to see the designer for the Level3 the designer show me errors, why?

If this a problem in my whay of programming or must placed an attribute before the method, please write my what I must write.

Thanks,

Claudiu

Is no aditional cod in constructor, and the problem, the bug is that the .Net not respond at anything, (task manager) - not responding, and the computer that I test have processor of 1,7GHz and 1Gb RAM.

Can you provide the sourcecode (constructors and Load only), and show us the error message that the designer gives?

1) publicclass Level1
inherits System.Windows.Forms

protected overridable SubLoadInformation()
'no code
end sub

private sub form_load(sender as object,e as EventArgs) Handles MyBase.Load
LoadInformation()
end sub

end class

2) public class Level2
inherits Level1

protected overrides Sub LoadInformation()
Dim sqlDataAdapter as new SqlDataAdapter(..,...)
sqlDataAdapter.Fill(_dataSet)
'with information resulted fill an listView
end sub

end class

3)public class Level3
inherits Level2

'nothing
end class

If is needed I can make a small project and attached. thanks

You forgot to paste the error message... (no additional code in the constructors?)
