Answer 1

Use the keydown event:

textBox.Attributes.Add("onKeyDown", "KeyDownHandler()");

Have KeyDownHandler() check the pressed key and if correct, submit the surrounding form or invoke an AJAX request. See keyboard codes at Javascript Char Codes.

Alternatively, textbox ID can be injected into jQuery from .aspx and assigned a direct keydown handler:

$('#<%=textBox.clientID%>').keydown(function (e) { /* Do server request; */ });
