Control in WinForms?

Question

Windows

Who can tell me what the name is and whether there is an element in the collection of Windows Forms controls that represents a standard textbox, but inside it there are fixed lines that cannot be edited, but only added (for example, from a modal window) or deleted. A good example is the address line in MS Office Outlook: in fact, not addresses are indicated, but the recipients themselves, clearly associated with the address. But you can't edit the recipient's name

Answer 1

There is no such thing exactly.
1. Inherit from TextBox or ComboBox (or see what they are inherited from) and implement what you need yourself
2. Look for ready-made solutions. Maybe even these will work for you:
AutoComplete-TextBox #1
AutoComplete-Textbox #2
