Well said sir.

He's absolutely right there, So here is using a TableView instead of
GridView
It uses TableView1.EditWith() in the Click event if column 1 is clicked to
show the SpinBox.
It then uses the TableView1_Save() event to save the SpinBox changes back
to the View.

' Gambas class file
Private $hSpin As SpinBox  ' this is the SpinBox (hidden)

Public Sub Form_Open()

  $hSpin = New SpinBox(Me) ' make a SpinBox and hide it.
  $hSpin.Visible = False

  TableView1.Columns.Count = 2
  TableView1.Rows.Count = 20

  For c As Integer = 0 To TableView1.Rows.Max
    TableView1[c, 0].Text = "Left text " & c
    TableView1[c, 1].Text = "0"
  Next

  TableView1.Columns[0].W = -1

End

Public Sub TableView1_Click()

  If TableView1.Column = 1 Then TableView1.EditWith($hSpin)

End

Public Sub TableView1_Save(Row As Integer, Column As Integer, Value As
String)

  TableView1[Row, Column].Text = Value

End

Another tip Shane, be wary of using Form_Show() to initialize stuff.
Form_Show() does not only trigger when a form is opened, it also triggers
again if the window is un-minimized and also various other reasons.

Adding controls to the form in Form_Show() event may re-add controls or
redo other initialization stuff unexpectedly/repeatedly.

It's better to use Form_Open() for things you strictly only want to do once
during form creation.

Good luck
