Create control at runtime

[shy_wani]

i've got this code to create control at runtime..
the problem is that i've forgotten the link and i can't refer to its documentation....
the problem is...i don't understand this line:
Dim parent As String = CStr(ds.Tables(1).Rows(0)("Parent"))

what does this parent refer to?

Dim options As New RadioButtonList
For Each row As DataRow In ds.Tables(0).Rows
Dim item As New ListItem
item.Text = CStr(row("Name"))
item.Value = CStr(row("Id"))
options.Items.Add(item)
Next
Dim parent As String = CStr(ds.Tables(1).Rows(0)("Parent"))
Select Case parent
Case "sideNav"
columnSidenav.Controls.Add(options)
Case "footer"
footerCoontainer.Controls.add(options)
Case Else
paceholderDefault.Controls.add(options)
End Select

~i wanted to learn more~

"parent" is the column name in that specific context, the line is going to return the 1st row parent column value to "string var"
