Listbox scroll

[Adam Klobukowski]

Hello.

/windows forms/
I'm marking listbox items as selected, and I'd like to scroll listbox to
a selected entry if it is off-screen. How can I do it?

Adam,

Setting ListBox.Selecte dIndex should automatically scroll the listbox
to the selected item.

Ok, but ListBox.Selecte dIndex is read only. Should I use property or
method of it? If yes, which one?

I tried something like this:
s_lv.Items[ret].Selected = true;
rozlacz.Enabled = true;
s_lv.SelectedIt ems[ret].Selected =true;

But it doesn't work :(

Damn I made mess ;)

It should be:

s_lv.Items[ret].Selected = true;
s_lv.SelectedIt ems[0].Selected =true;

And it is not a lisbox but listview and it has multiselect=fal se property.

ListBox.Selecte dIndex is read/write, so just set it to the zero based index
you want to be selected in the listbox.

s_lv.SelectedIn dex = 3;

Adam,

Try this:

this.listView1. Select();
this.listView1. Items[ret].Selected = true;
this.listView1. EnsureVisible(r et);

The ListView has to be selected before it will honor a request to
programmaticall y select an item (I don't know why...).
