If I try to get the index of the B4XSeekBar in CustomListView I get the error:
B4X: 
Sub B4XSeekBar1_ValueChanged (Value As Int)
    Dim index As Int = allclv.GetItemFromView(Sender)
    Log(index)
End Sub
B4X: 
Error occurred on line: 209 (Main)

XCustomVistView cannot click on B4XSwitch and get the current panel in the list

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 Sub BtnSchedEnable_ValueChanged (Value As Boolean) Try Dim MyIndex As Int...
www.b4x.com

Edit: Disregard. The custom view base panel is now Public ... see below.

This will now work ...
B4X: 
Sub B4XSeekBar1_ValueChanged (Value As Int)
    Dim sb As B4XSeekBar = Sender
    Dim index As Int = allclv.GetItemFromView(sb.mBase)
    Log(index)
End Sub

Code by @mangojack in post 3 works well, but Erel in post 4 makes reference to a another thread. Does that mean it is a confirmation of mj's code or there is a different way of achieving the same result via the thread link of post 4. I tried it, but could not figure out a different way other than what mj showed.

I had read that thread posted by @Erel earlier covering the use of .Tags .. but thought due to mBase being made Public (following updates)
it was now not necessary /superseded (to use the .tag method).
