    HI,
    Please first elaborate your problem in detail, so that we can help you.
    One thing I understood with you question is that you want last E-ID of registered student.
    For that you can write a query like this and bind the result to your Enrollment ID textbox:
    select MAX(E-ID) from StudentTable
    Hope it helps.

    Sorry sir but i just want to ask you that i have 3 combo box 1st one is for Branch Name 2nd one is for Courses 3rd one is for session, i have a text box also in which i want an enrollment id.
    Suppose if i select the branch name 'BASE' and among many courses i have chosen 'JAVA' and the session selected 14-15 and if 15 student are registered for java course already then the E-ID should be BASE/JAVA/14-15/0016

    Hi Sachin,

    Refer the below..

    In 3rd combo box selected index change event
    {
    //////First get latest E-Id from databse using database call(select MAX(E-ID) from StudentTable ) and store in one variable for Ex. say ' Id'.
    int Id= //database call to get maximum id
    /////Declare a string as Result for textbox value,
    Result = 'dropdownname.Text' + '/' + 'dropdowncourse.Text' + ' / ' +'dropdownyear.Text' + '/' + 'E - ' + 'Id'

    }


    Hope this will help you
