Answer 1

关闭textbox Autocomplete功能

<asp:TextBox Runat="server" ID="Textbox1" autocomplete="off"></asp:TextBox>

Answer 2

Apart from implementing your own autocomplete, such as by overriding OnTextChanged and showing a list, the only options to control the behavior of autocomplete on a WinForms TextBox are given by the AutoCompleteMode property and the enumeration of the same name . See C# AutoComplete for a related question.

Third party text boxes may have more options but I am not aware of any that do.
