I was asking you that, you want option to list out all search value while typing in the text box..lets say you are searching the country details by country name...then when you start typing the search criteria lets say..i then automatically India,Iran should be listed out to select it..

Is this you are looking for?

Hi,
  You want auto complete option for input search criteria or after typing your search criteria in textbox it should search automatically and display the result in the grid.
