    3. COThe messages inside the div tag when exceeds the hieght of the div tage ie, my div tags hieght is 250px if the messages exceeds this height then if i scroll to see the messages in top i cant view it because always my scroll position is at bottom so once i move the scrollbar to top it immediately comes to the bottom, i have kept the scroll bar to be always at bottom, then only the user can instantly see his messages i am expecting answers from experts

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
