If the other spread sheet is on a different Form you can access that Form in the same application and also get the values from the main Spread sheet.
Private Sub FpSpread1_CellClick(ByVal sender As Object, ByVal e As FarPoint.Win.Spread.CellClickEventArgs) Handles FpSpread1.CellClick
If e.Column = 1 And e.Row = 1 Then
FpSpread2.Visible = True ' if spread2 is on the same Form
Form2.Show() 'if Spread2 is on another Form
FpSpread2.Visible = False
Let me know if this is not what you are looking for.
