First of all, I'd use the Java forum for this question, this one is for J2EE.

After that, what is the question?

Cheers,

hi,
if i select the header(checkbox) all the check boxes in each row will get selected..if i deselect any of the checkbox in a row it should deselect the header(checkbox)..
but here it not doing it so..plz solve my problem

 

[Diancecht]

I'm sorry but I don't think you can expect others to solve your problems. Maybe you can get answers to specific questions if you follow some guidelines:

1.- Post only relevant code, indented and explained: probably nobody will read a lot of plain code
2.- Explain carefully what you tried, the errors you got, the behaviours of your application

Cheers,

This can cover point 1, you still miss point 2.
