ListView and FocusedItem

[Tore Stensby]

Hi.

We are developing an application for the Symbol 8100, with a (almost)
complete hardware-keyboard. And after the release of SP2 the use of the
keyboard works pretty well.

But im struggling with one issue:
When my form loads, i read and fill a he listview, selects the last item,
call the ensurevisible, and forces the focus to the listview. Then i want my
user to be able to navigate up and down in the list using the up and down
keys on the keyboard. But when i use

Sorry, some more should be here:

But when i use the up/down-keys, the listview repositions to the first item
in the list. And trying to call the FocusedItem, a NullReferenceException
occurs.

If i click the selected item with the stylus in the listview, the focuesitem
is set, and the navigating works perfect. Trying to manually set the
FocusedItem dont work, the property is ReadOnly.

Am i missing something when working with the listview this way?

Hello Tore,

You need to set the Selected and Focused properties of the listviewitem to
true. For example,

this.listView.Items[this.listView.Items.Count - 1].Focused = true;
this.listView.Items[this.listView.Items.Count - 1].Selected = true;

Please let me know if this does not help.

Best regards,
Sergiy.

Hello Tore,

You need to set the Selected and Focused properties of the listviewitem to
true. For example,

this.listView.Items[this.listView.Items.Count - 1].Focused = true;
this.listView.Items[this.listView.Items.Count - 1].Selected = true;

Hmmm, that simple.... Yes, it works! Thank you.

And together with:
this.listView.EnsureVisible(this.listView.Items.Count - 1)
You are sure that the selected and foucesd item is visible in the list...
