.NET Forum / Windows Forms / Design Time / June 2004inherited form
i have a generic form with alot of controls on it, when i inherit a new form, i can not see the design of my new form on the visual studio and get an error on designtime. Error is: The designer could not be shown for this file because none of the classes within it can be designed. The designer inspected the following classes in the file: form2 --- The base class 'form1' could not be loaded. Ensure the assembly has been referenced or built if it is part of the project. ok, i do it. i dont know if that is right method to solve this problem: i copy the properties that belongs to form1 (such as size) and paste to form2, now i can see form2 on the designer. > i have a generic form with alot of controls on it, when i inherit a new > form, i can not see the design of my new form on the visual studio and get [quoted text clipped - 8 lines] > form2 --- The base class 'form1' could not be loaded.

(In your Solution Explorer, right-click References->Add Reference ... and browse to a dll or exe where form1 is defined.  SignatureHappy coding! Morten Wennevik [C# MVP] Morten, i do not use any dll, i just create form1 with visual studio designer and inherit form2, my problem was i can not see form2 on the designer, i solved it as i explained in my other post. thnkz.. > Hi e-mid, > > You need a reference to form1 in your project.

The inherited Form will look slightly different with a small blue arrow box in the upper left corner of all inherited controls, putting a control on Form1 should cause it to appear on Form2 too (might take a few seconds before it shows). SignatureHappy coding! Morten Wennevik [C# MVP] no, i dont even know about it :) , but i will give a try now thnkz > Did you use "Add Inherited Form" when creating Form2?

Are you sure you inherit from the correct form1 (maybe it should be Form1 or something else) SignatureHappy coding! Morten Wennevik [C# MVP] yes, "add inherited form" does the same thing i do, i am not sure about what was wrong, i deleted some controls on form1 on the code editor, before inheriting form2 , maybe the problem was about it. anyway, there is no problem now. > Come to think of it, this way is exactly the same way as creating a new form and changing the inheritance from System.Windows.Forms.Form to Form1.
