Question

protected void pnlFriends_Click(object sender, EventArgs e)
{
    ClickablePanel pnlFriends = sender as ClickablePanel;
    lvFriends.SelectedIndex = ((ListViewItem)pnlFriends.Parent).DisplayIndex;
}

Does not hit the following:

protected void lvFriends_SelectedIndexChanging(object sender,  
ListViewSelectEventArgs e)
{
    GetConversation(lvFriends.DataKeys[e.NewSelectedIndex][0].ToString());
}

How come? I used to get this working with WinForms using .Selected = true; However, it looks like there is absolutely no way to dynamically fire the ListViewSelectedIndexChanging event.

Any ideas how can I get this to work properly? Thank you.

EDIT

I am trying to select a ListView Item, and when the index changes. I am trying to populate a second ListView on the same page. I need to handle the first event when the index changes.

UPDATE (RESOLVED)

protected void lvFriends_SelectedIndexChanging(object sender,  ListViewSelectEventArgs e)
{
    lvFriends.SelectedIndex = e.NewSelectedIndex;
    lvFriends.DataSource = Friendship.GetFriends(User.Identity.Name, false);
    lvFriends.DataBind();
    GetConversation(lvFriends.DataKeys[e.NewSelectedIndex][0].ToString());
}

protected void pnlFriends_Click(object sender, EventArgs e)
{
    ClickablePanel pnlFriends = sender as ClickablePanel;
    lvFriends.SelectItem(((ListViewItem)pnlFriends.Parent).DisplayIndex);
}

^ Works flawlessly.
I guess somehow, .SelectItem triggers ListViewSelectEventArgs and we would have to handle it by setting .SelectedIndex = e.NewSelectedIndex; and then rebinding the data to display the selected item properly.

Now what I can do with the code above is just call this -> lvFriends.SelectItem(int);

Answer 1

protected void lvFriends_SelectedIndexChanging(object sender,  ListViewSelectEventArgs e)
{
    lvFriends.SelectedIndex = e.NewSelectedIndex;
    lvFriends.DataSource = Friendship.GetFriends(User.Identity.Name, false);
    lvFriends.DataBind();
    GetConversation(lvFriends.DataKeys[e.NewSelectedIndex][0].ToString());
}

protected void pnlFriends_Click(object sender, EventArgs e)
{
    ClickablePanel pnlFriends = sender as ClickablePanel;
    lvFriends.SelectItem(((ListViewItem)pnlFriends.Parent).DisplayIndex);
}
