1. which is lightweight and better way of design ?
A dropdownlist with 500 records OR a text box with ajax auto complete ?
but if i use the auto complete then i have to 1) validate the data and 2) also fetch a ID of the record and keep in a variable


2. which is light weight and better way of design ?
a. repeater control with custom paging and sorting
b. Gridview with custom paging and sorting

data display is in tabular format only
