    Hai Nadeem,
    Its very difficult to find out the issue with the whole code as we can't run this code in our system due to non-availability of database and other related code.
    You can debug the application and check if you are getting any error message so that we can provide you the solution for the implementation.
    Hope it will be helpful to you.

    i think i have posted all the unneccesary code but when i posted i other blogs they were asking the whole code..so that it be easy to find out..my problem or implementation

    //////-------//////////
    under item command event
    if(rows.length > 0)
    {
    i think here the quantity column value can be doubled...
    }
    but i could not get what logic should be implemented
