Hello sir/madam


I am designing my own Email System like Gmail. In this I want to use word prediction technique in Compose mail TextBox.

I mean when Someone type something in compose mail textbox ,it should automatically retrieve values from database.

That's fine,, With PHYSICAL KEYBOARD it is happening successfully.  I have used Jquery Autocomplete textbox technique.

MAIN PROBLEM IS:-

When I have also used google virtual keyboard facility in my project. When I type something from virtual keyboard Autocomplete textbox does not work,It does not retrieve values from database, but when i use physical keyboard it works.

WHAT SHOULD I ADD IN MY CODE TO WORK IT WITH VIRTUAL KEYBOARD SUCCESFULLY?????????

MY CODE IS:-

Default.aspx:-
