You can call ListView.SetSelection to make a specific item visible.

It might be simpler to use CustomListView which gives you more control.

ok, but i need that the 2 listview scroll together, Please can you post a example?, Or I select the color of text of only a one line of the listview?

Could you describe exactly what you want to do? Selecting one item from the first and then scroll to a matching in the other listview?

You cannot change the color of the selected item with a listview!

Consider to use a CustomListView instead. Here you have much more control.

Hi DLZ,

if I'm not wrong, the ListView object miss a ScrollChanged event so you have no chance to intercept scrolling on first list to reflect as an action on your second list.
Both Erel and Manfred suggested to have a look on the CustomListView object which is built around a ScrollView which in turn sports a ScrollChanged event.
You may want to sync the second list "position" (based on value from first list) in that event to have your two lists scroll together.
