When creating controls and using them in the form designer, I repeated get errors stating one of the control's methods, or a method within the constructor or load event, does not exist when the code compiles and runs without any problem.

Here is an instance:
I have a control library, lets call it MyControls.DLL, that contains the control Axis. Axis has a property called AxisMarkPositions with the attributes DesignerSerializationVisibility = Hidden and Browsable = false.
In a separate solution I have a project, ControlProject, that references MyControls.DLL. FormProject contains a user control, Ruler, that has on it an Axis control. The Paint method of Ruler uses Axis.AxisMarkPositions to determine drawing boundaries. In a second project, FormProject, in the same solution, is a form that has on it a Ruler control. When I attempt to open this form in the form designer I get the error:
Method Not Found: Axis.get_AxisMarkPositions(). Again, all of this compiles and runs fine without any problems.

Is there anything I can do to keep from getting this error?

I am using C# in Visual Studio Professional 2008, .NET 3.5.

Thank you

Hi Flarg,


Please try to set the DesignerSerializationVisibility attribute to true, and rebuild the solution. Let me know if this can solve the problem.
