Hi Ashwin,


1. Develop one ActionResult with Json return type and write code to get data list from database and return the same.

2. In View write jQuery keypress event handler and inside that write jQuery Ajax code to request list of record from json Method.

3. Finally iterate through each data from json array and validate input with that, if found populate error message and return false;
