Deleting the textbox

Question

Hi,
in my windows form I deleted the text box, in the design file, and put a combobox instead. But when I run the application I see again the textbox, not the combobox. Even if I only delete the textbox and put nothing, I still see the textbox. Can anybody tell me please what is the problem?
Thanks

It sounds like the designer has lost synchronization with the actual code.

First try exiting out of VS completely, going back in and rebuilding the solution.

If that doesn't solve the problem, I'd open the Form1.Designer.cs file and do the following:

1. If the textbox and combobox are defined as private fields towards the bottom, delete their definitions.

2. Open up the Designer generated code, look in the InitializeComponent() method and remove any code which involves the textbox or combobox.

Now open up Form1.cs, remove all eventhandlers or any other code that involves the textbox. Also remove any eventhandlers or other code for the combobox but save the code to notepad, say.

In the unlikely event that you have other files which contain code for the textbox or combobox, do the same for them as for Form1.cs.

Rebuild the solution.

Now open up the designer again, add the combobox back, add back any eventhandlers from the properties box, add back the code from notepad, rebuild and run.

Thank you to both of you. I just changed the code and removed the textbox everywhere in the cs code and now it's ok. Thank you Sam, I will have your suggestions on mind mabe for some other time, what to be aware of when making the code.

The first thing I would is to try a rebuild, as Vulpes suggests. Or perhaps I would first look at the date and time on the executable to see if it is in the future or if it is from further in the past (such as the previous day) than you have been attempting to solve the problem.

If you have been messing with the date and time for your computer, then that could cause the problem. A rebuild will solve it.

If the date and time of the executable is further in the past than you expect, then it could mean that VS is confused and building the wrong thing.

If none of that solves the problem, then I would put something in the code that can determine for sure that the build is doing what it should. For example I might put a MessageBox in the form load event. If that last change shows that the build is being done, then I would proceed as Vulpes suggests.

Hopefully you haved already solved the problem and everything I said is not relevant.
