passing variable from child to parent - possible ?

[mark]

I have a main form, and i have another form i need to call on a button
press,
then id like the result of the child form to pass data back to the parent -
without losing any data previously entered
on the parent - is this possible ? ( my main parent window is starting to
get quite cluttered)

cheers

The problem is in not losing the "parent" data... Are these windows open
in the same browser window or are you opening the "child" in a new
window? If its the same just save their existing data, in a
db/viewstate/session/etc, and then when you reload it retrieve it.
If not you will have to force the "parent" to postback to get it to
refresh, and with the viewstate enabled you should get the pre-entered
data to remain

looks like ill be forced to save on opening the child, either that i
redesign the whole form to be more modular
problem is - i have to pass an ID to the child that doesnt exist until the
parent is saved - so things are getting more complicated
than in reality they should be

Mark,

The standard way is to call javascript method showModalDialog for the child
form. The child form can pass back data in javascript window.returnValue
property which the parent form will get as a return value of the
showModalDialog call.

thanks
