Class: Cascade Dropdown 3 Levels

The Class can be used to Fetch the record from the database and load it in 3 different list boxes, where are the Values of the child will be depended to the Parent. Here we have 3 Levels, Like illustrated below.

Type —————–> Brand ————-> Model.

Its like when we select the Type respective Brand list will be loaded, when the use makes the choice in the Brand dropdown then the Model is made avaiable based on the previous box value.

The Class is Similar to my Cascade DropDown , the Difference between both ths class is the level of List boxes. In my older class, I have given only two list boxes, where here i am dealing with three at same time.

Reason : The Class will avoid Page reload while adding the data to the List Box. So the Users will not feel bad using your page. They will not have any burdens
