this is the code, button1 works but the B4XSwitch does not (BtnSchedEnable)

is there a way to get the index with GetItemFromView on a B4XSwitch? or any other means?

Regards,

Mike

B4X: 
Sub BtnSchedEnable_ValueChanged (Value As Boolean)
    Try
        Dim MyIndex As Int =CLVPoolTC.GetItemFromView(Sender)
        ToastMessageShow(MyIndex,False)
        Dim TCi As TCItem = CLVPoolTC.GetValue(MyIndex)
        TCi.Tue.TextColor= 0xff6a5acd'
    Catch
        Log(LastException)
    End Try
End Sub
Sub Button1_Click
    Try
        Dim MyIndex As Int =CLVPoolTC.GetItemFromView(Sender)
        ToastMessageShow(MyIndex,False)
        Dim TCi As TCItem = CLVPoolTC.GetValue(MyIndex)
        TCi.Tue.TextColor= 0xff6a5acd'
      
    Catch
        Log(LastException)
    End Try
End Sub

1. Don't use toast messages for debugging. Use Log instead.
2. The Try / Catch blocks are not needed and will only make it more difficult to fix the problem.

A custom view class is never a view by itself.
Unfortunately the base view of B4XSwitch is not public. I will change it for a future version.
You can instead do something like:
B4X: 
'when you create the item layout
Panel1.LoadLayout(...)
B4XSwitch1.Tag = Panel1

You can then use it with:
B4X: 
Sub BtnSchedEnable_ValueChanged (Value As Boolean)
Dim sw As B4XSwitch = Sender
Dim MyIndex As Int =CLVPoolTC.GetItemFromView(sw.Tag)

thanks Erel,
Interestingly that did not work either but if i set it to
B4X: 
B4XSwitch1.tag = Button1

then it works like a charm.

now i just need to tidy it up
