Which naming convention do you use and why?
I like to use employeeNameTextBox, because:
Ideas:
Avoid encodings/abbreviations.
The name should stand out from similar names in the same scope. Make the unique-most part the left-most part. I suspect you have several text boxes, but only one is the employee name.
Avoid needless context. Are all the names on this page about employees? Is it an "employee" page? Then EmployeeName is redundant. NameBox or NameControl should be plenty.
Avoid needless context: do you have names that are not controls? If so, "Box", or "Control" is useful, otherwise not so much.
