I had a problem on focusing the textbox during async postback upon key enter using IE 10 or 11. Sometimes the text box is being locked and needs to click outside of the textbox and click again the textbox to bring back the focus.
Note: It works in Chrome and firefox but not in IE 10 or 11.
The expectation will be, everytime the user will hit enter inside the textbox then it will automatically have an async postback then it will focus and select again the text inside the textbox. Hence, There will be a javascript alert called before the setfocus
during asycn postback.
