示例1: UOMID_SelectedIndexChanged

        protected virtual void UOMID_SelectedIndexChanged(object sender, EventArgs args)
        {
            // If a large list selector or a Quick Add link is used, the dropdown list
            // will contain an item that was not in the original (smaller) list.  During postbacks,
            // this new item will not be in the list - since the list is based on the original values
            // read from the database. This function adds the value back if necessary.
            // In addition, This dropdown can be used on make/model/year style dropdowns.  Make filters the result of Model.
            // Mode filters the result of Year.  When users change the value of Make, Model and Year are repopulated.
            // When this function is fire for Make or Model, we don't want the following code executed.
            // Therefore, we check this situation using Items.Count > 1
            // Since both of these feature use javascript to fire this event, this can be skip if the event is fired by server side,
            // so we check if it is not postback
