. This property is used to check whether the page is being loaded and accessed for the first time or whether the page is loaded in response to the client postback.
Consider two combo boxes
In one lets have a list of countries
In the other, the states.
Upon selection of the first, the subsequent one should be populated in accordance. So this requires postback property in combo boxes to be true.
