Thread: Form Design Error

Thanks a lot....

Somewher in your copying you have omitted an allocation or reference so the main form does not have a variable called TextBox1. Take a look at the form and also the code behind to see which parts are missing. You would probably have found it simpler to add a new text box from scratch rather than doing it this way.

Delete the textbox and copy it again. Sometimes, Visual Studio suffers from selective amnesia in that it copies only a part of the code and leaves the rest.
