ListItem

Tsvrc.UI.ListItem is the base class for a single row in a TsvrcList. Its generated shadow is TsListItem. You don't create or destroy instances yourself: TsvrcList instantiates, binds, unbinds, and destroys them as its pool and pagination require.

Usage

Subclass it and override the two lifecycle hooks:

public class MyRow : TsListItem
{
    protected override void _OnBind()
    {
        // _itemData, _dataIndex are populated here; populate your UI children from them.
    }

    protected override void _OnUnbind()
    {
        // _itemData and _dataIndex are STILL valid here — clear UI state before they're cleared.
    }
}

_OnBind runs when TsvrcList assigns this instance a row of data (_itemData, a DataDictionary, and _dataIndex, its position in the full data list, not necessarily its position on the current page). _OnUnbind runs when the list is done with this instance, before _dataIndex/_itemData are actually cleared, so your override can still read them one last time if cleanup needs to reference which row it was.

IsBound reports whether the item currently holds live data: false between Unbind() and the next Bind() call, useful for guarding UI logic that shouldn't run on a pooled-but-currently-unbound instance.

Wiring selection

Wire _OnItemPressed to a Button's onClick. It's a no-op if the item isn't currently bound (guards against a stray press on a pooled item mid-transition). Otherwise it calls back into the owning list's OnItemSelected(dataIndex), which is what actually records the selection and emits TsvrcList.OnItemSelectedEvent. ListItem itself never emits that event directly; it only triggers the list's own handling of it.
