That is what the autopostback property does.

If you want to prevent page refreshing, set autopostback as false. And do the selection of all checkboxes at client (via jquery).

anurag19289 11-Sep-13 23:28pm

so if i want to do it through server side...then this autopostback property has to be true ? is it correct ?
