I have 2 ddlb the 2nd will be filled up depending on the selected values of the 1st. The 1st ddlb has 3 values. When user selects any of the first two it will fill up the 2nd ddlb with hardcoded values so I just use javascript for this. But when user picks the 3rd I have to retrieve data from the databases to fill the 2nd ddlb. So I have to use autopostback on this. The problem is I want it to be when user selects any of the first 2. It will just call javascript and not autopostback. If he chooses the 3rd it will autopostback and retrieve from database. Is this possible
