Javascript postbacks and viewstate

[burn1down]

hey fellow nerds,

i am putting the finishing touches on a web application. I have two
frames (not iframes) the top frame has a flash animation naviagation
system, while the bottom frame has a infragistics supped up datagrid.

When the user clicks on my flash menu i am calling a javascript
postback of the
frame with the datagrid.

parent.frames._bottomFrame.__doPostBack(command, args);

now on the load i check to see if its a postback, grab the args from
the Request.Form.Get("__EVENTTARGET") &
Request.Form.Get("__EVENTARGUMENT")

everthing almost works as it should but.. it is not saving any
information (i.e selected row in the datagrid).
