[Gambas-user] DataSource

[Martin]

The answer is .Create

In this example, I use a temporary control to edit the data and then 
delete the control, you could hide it instead of deleting it.
If you already have controls on your form, simply use .Create

Sorry but I couldn't find a way to do it without a data control.

Public Sub Form_Open()


   Dim tb As Table
   Dim fd As Field
   Dim dt As DataControl

   DataSource1.Connection.Open
   DataSource1.Table = "clients"
   DataSource1.Filter = db.Subst("cname = &1", "martin")
   DataSource1.MoveFirst

   dt = New DataControl(DataSource1) As "dat"
   With dt
     .Name = "temportal"
     .Field = "cphone"
     .Value = Format(Now(), "hhnnss.u")
   End With
   dt.Refresh

End

Public Sub Button1_Click()

   Dim tdat As Control

   DataSource1.Create
   For Each tdat In DataSource1.Children
     If tdat.Name = "temportal" Then
       tdat.Delete
     Endif

   Next
