How can we retrive 3 combobox values and show it together in a textboxSir i will attach the project below and the problem is that i have 3 combo box that is branch name, Course and Year after that 2 textbox for enrollment id and Registration Number. Sir i want that when user select the combobox values as like branch name is IKN,Course is DCA and the year is 14-15 then automatically the enrollment id generated as like <Branch Name/Course/Year/The last registered number according to particular course>
sir the last registered number is according to the particular course as like there are 40 student are enrolled for DCA course then the number is 0040.
After that the Registration number is also generated like this (Branch name/Total number of student registered). Sir this total number is the number of total student get enrolled.
