hi,

Place all the student related fields in one panle and all the employee related fields in one panel.

When you click student radiobutton then set student panel visibility to true

When you click employeeradiobutton then set employee panel visibility to true

When you load page for first check one radiobutton by default and make corresponding panel visible


Hope this helps,

Thanks & Regards
