I have a column with employee Id and employee name.When i enter the EmployeeID in the textbox, the employee name should be automatically populated from the database in the second textbox. Please Help

You need jquery.
Fire onblur even on first textbox entered
call server page using jquery to fetch data from database based on first input
get response and fill second box with response
