updating a record using a dataset, multiple forms

i would like to update a record using a dataset on two forms.

form1 has a list of all the values that are return. the user double clicks on a record and form2 pops up with a textbox so that the user can type in the new value...
i can pass the whole dataset to form2 and have form two update it. but i dont want too seeing there are alot of records. is there an easier way of doing this? how about binding the textbox on form 2 to the dataset on form1? the dataset is named oDataset and is declared in a module.

Dim frmform2 As New form2(oDataset.Tables("ServerList").Rows(Me.BindingContext.Item(oDataset.Tables("ServerList")).Posit ion))
frmform2.Show()

on form2 i use a datarow to update the record that form1 puts into the textbox (above statement)
