B4J Question [SOLVED] Customlistview jumps to top

[Revisable5987]

If I set a button as Visible = False the CLV will jump to the top.

I can make the clv return to the correct place with 'VPosition' but the list first moves to the top and then to where I want it.

Is there anything I can do to stop the clv moving in the first place? using sleep(300) helps, but not always.

Example project attached. Scroll to the bottom and press the button.

I think that the best you can obtain is using:

btn.Visible = False
Sleep (0)
CustomListView1.JumpToItem(CustomListView1.Size - 1)

It seems to be a bug, so without changing the xCustomListView source code...!

Tricky indeed. It is related to the focus moving from the clicked button to the first button.
Workaround is to explicitly set the focus:

btn.Visible = False
p.RequestFocus

I ran into a similar problem where I wanted to jump to the bottom of list and it would not respond. After stuggling a little, I solved it by using:

Dim n As Int = CLVConversation.size         
CLVConversation.JumpToItem(n - 1)
'next 2 lines needed to ensure jumpto last line
Sleep(0)
CLVConversation.JumpToItem(n - 1)

I am not quite sure why it works though....
