I know this is an old question  but I think this is the definitive answer   listViewRamos Items i  Focused   true  listViewRamos Items i  Selected   true  listViewRemos Items i  EnsureVisible      If there is a chance the control does not have the focus but you want to force the focus to the control  then you can add the following line   listViewRamos Select      Why Microsoft didn t just add a SelectItem   method that does all this for you is beyond me

Most likely  the item is being selected  you just can t tell because a different control has the focus  There are a couple of different ways that you can solve this  depending on the design of your application    The simple solution is to set the focus to the ListView first whenever your form is displayed  The user typically sets focus to controls by clicking on them  However  you can also specify which controls gets the focus programmatically  One way of doing this is by setting the tab index of the control to 0  the lowest value indicates the control that will have the initial focus   A second possibility is to use the following line of code in your form s Load event  or immediately after you set the Selected property   myListView Select      The problem with this solution is that the selected item will no longer appear highlighted when the user sets focus to a different control on your form  such as a textbox or a button   To fix that  you will need to set the HideSelection property of the ListView control to False  That will cause the selected item to remain highlighted  even when the control loses the focus   When the control has the focus  the selected item s background will be painted with the system highlight color  When the control does not have the focus  the selected item s background will be painted in the system color used for grayed  or disabled  text   You can set this property either at design time  or through code   myListView HideSelection   false

I think that the problem and the solution was descripted by cody gray  I ve an additional note   Please check the focus of the specified listview item  and the control    I could set the focus and the selection with the following lines of code    this listView1 Items 1  Selected   true  this listView1 Items 1  Focused   true    But the focused control was a condition

if  listView1 Items Count  gt  0        listView1 Items 0  Selected   true      listView1 Select        list items do not appear selected unless the control has the focus  or you set the HideSelection property to false
