Dear IS,

I'm sorry for the unclear question I've got.
First of all, I've searching for all Hierarchical Sample in your Installation Sample.
And the nearest possible way to bind grid - with what I intend to do - is in "Unbound Hierarchical.aspx"
(I'm sorry, I really don't know how to say it with word)

But in your sample, the child data that would be binded, is matched to Parent data in one-by-one way.
I intend to use the unbound way, but with queried datatable.
The child grid could perform complete data manipulation (Insert/Delete/Update), and again, with a queried command, not with ISDataSource or SQLDataSource,
because some data that viewed in this grid is just a master description data.

Yesterday, I found the way to perform data checking for Child grid with Batch Update.
But still, I had no idea how to show the Child data.
Should I bound it to its parent's data, one-by-one?
Is there any simple sample for this unbound way ?

Hope this a little bit more clear for you.
Thanx.
