Are you trying to say that the After Picking event isn't fired at all?

Set ListView.SelectionColor out of the AfterPicking block...you can set it before picking.

I have the same behavior if set the SelectionColor inside the AfterPicking block, but it works if I set it out of the block (I don't know if it's a bug or not, but it's a bit strange behavior).

As I mentioned earlier, after changing any properties, the ListView is reset, and therefore the display of the selected item is also reset. You can get around this by reselecting the item programmatically.

Thanks Patrik...I hadn't understood you...now I do. It works.

This extension is not an alternative to ListView. It just adds a few extra methods to the ListView.

Go Scroll Yourself! blocks only (No extensions, No JavaScript)

This tutorial is intended for people who need to display a heavily customized scrollable window into a large table. It can also be used as a CardView.

If you have a wide table you could try formatting it as YAML

I don't see what is happening in the Web1.GotText event.

[Ondrej_Ruz]

Hello

gListCelaDB is: ["1;aaaaaaaa","2;bbbbbbb","3;cccccccccc","4;dddddd"]

Remove the call to the "createList" procedure from the Initialize event. And add this call in the Web1.GotText event, under label6.Text....
