Is it possible for 1 check box to check other check boxes?

[mda29018974]

Lets I have these check boxes under a selection header: A, B, C, D and "Select All". When user check "Select All", it should also check A, B, C and D. Is it possible? Thanks in advance!

Sure, but should it un-check them if the "Select All" box is un-checked itself?

[mda29018974]

Yes. Select all box will have the control over the other check boxes. For better understanding I am attaching a screenshot:

If possible, please tell me how I can do it. Thanks.

As the Mouse Up event of the "Select All" field enter something like this:

this.getField("A").checkThisBox(0, event.target.isBoxChecked(0));

this.getField("B").checkThisBox(0, event.target.isBoxChecked(0));

this.getField("C").checkThisBox(0, event.target.isBoxChecked(0));

this.getField("D").checkThisBox(0, event.target.isBoxChecked(0));

etc.
