storing session variable to parent object

[kotinkarwak]

Hi,
Trying to understand session variables across components. In instances where you embed components in other component, how would you pass variables from child to parent.
I have a grid component this is embedded into a UX. The grid is read only but with a button that has (compute current row data) enabled from which I am trying to set to parent's namespace a session variable.
How can I achieve this?

I am not sure this will work, but the concept here. I can test it in am to see if it works.
from the grid
get the id of the parent object
get the value you want to set in the ux session
in the ux have a non bound non updatable field
populate that field using the id you got.
then in the ux on that field's onChange event fire up an ajaxcalback to set session variable.
long winded, yes. because I am not a pro programmer.

parent's namespace a session variable.

is it something different, I think session variables are common to all components. you should be able to set the session variable from the grid itself and make it available to the ux.

On row select/click on the grid I am setting this in an xb function
Session.variable01 = "testing"

but can't see it from the ux. Tried an alert either of session.variable01 or simply variable01.

how would you pass variables from child to parent.

this is not as easy as passing value from the parent to child.
the parent know the children but for the child to get the id of the parent is difficult since the child can be a one of many or few.
selwyn has a video on how to do that. i will look for it and post pack as soon as i find it

and the video next in version 10 will show you how that is done.
for me it is easy to pass variables via window object. every browser supports it. does not need alpha server help to keep the session.

Thanks Gandhi,
The parentGridAlias command is helpful.
Have managed the test I was doing in ajax callback as follows. It allows me to setValue to a control in parent UX control for the grid

...
js = js + "var myParent = {grid.Object}.getParentObject();" + crlf()
js = js + "myParent.setValue('txtCustomerID','" + e._currentRowDataNew.CustomerID +"');" + crlf()
...
Thanks
