 GIS_ControlLegend->GIS_Layer = lv ;

only this row I was able to find.

I need to know the mouse clicked item like in LIstBox.
In TListBox component I can use, ItemIndex to get the selected item name, but how can I do this 
here?

It is not so easy, because you can have layers, sublayers, renderings, etc. So it's not a simple list box. You can use LayerSelectEbent, LayerActiveChangeEvent to track item selection.
