Add View (control) at Runtime

[TedN]

Is there a tutorial or example of how to add a label (or any view) at runtime.

AddView seems pretty straightforward but I can't seem to get it to work.

Sub EditMode()
     Dim lblControls As Label

     AddView(lblControls, 10, 20, 100, 200)
End Sub

I'm getting error: Undeclared variable 'addview' is used before it was assigned any value.

You need to specify either "Activity" or the Panel you want to add the view too

Activity.AddView(....

You also need to Initialize the View before you add it.

lblControls.Initialize("EventID")

Thanks for reply. I get no errors now but nothing appears on the emulator.

My revised code is as follows:

Sub Activity_Create(FirstTime As Boolean)

   Activity.LoadLayout("Main")
   EditMode
   
End Sub

Sub EditMode()
   
   Dim lblControls As Label
   lblControls.Initialize("controls")
   lblControls.Color = 255
   lblControls.Text = "TEST"
   lblControls.TextColor = 0
   lblControls.BringToFront
   Activity.AddView(lblControls, 10, 20, 100, 200)
   
End Sub

That is because you have a transparent label on a black background with black text.

Try modifying the line to

lblControls.TextColor = Colors.Cyan

and you should see the text.
