Passing values from datagrid to form and form to datagrid

[SanjayKumarDey]

I have a vb.net datagrid bound to a dataview on a windows form. I want to
use the datagrid to display and filter a list of items , but since the data
is complex, I don't want the user to edit the item using the datagrid. I'd
like to have another form display when the user double clicks the desired
row in the datagrid, and have that form display details for the selected
datagrid row.

I'm having problems figuring out the best way to pass the selected row on
the first form to the second form. All of the data (including data from
related tables,) is already populated in the underlying dataset on the first
form, so I'd like to pass the dataset also.When Second form will be opened. I would like to editi data on the Second Form. After the data edited on the second form one 'OK' button shuld be there on the second form.So that I would click the 'OK' button then the second form would be closed and the edited data of the second form should be reflected on the first form and then I save the first form with the edited data. Can anyone recommend the best
and/or easiest way to accomplish this?

Thanks!
