C#: How to select the top item in a listview after sorting

Question

I'm filling my System.Windows.Forms.ListView with results from my database as such:

foreach (DataRow row in theTable.Rows)
{
    ...build item from row..

    myListView.Items.Add(item);
}

And then I want to sort my listview in a different order than the rows come back from the DB, so I call

myListView.Sort();

But then when I want to go to select the top item in the listview it won't work, it selected something other than the top item:

myListView.Items[0].Selected = true;

Makes sense since the Items collection is added to in the order of the rows from the table iterated through in the foreach loop.

Using myListView.TopItem.Seleted = true doesn't work either.

So how do I go about selecting the topmost item in the listview AFTER I've sorted it?

Thanks for any answers.

Answer 1

Are you sure the list view is currently selected? If it's not selected you will not see the item being selected.

The following code seem to be working:

    private void Populate(object sender, EventArgs e)
    {   
        listView1.Items.Add("D");
        listView1.Items.Add("B");
        listView1.Items.Add("A");
        listView1.Items.Add("C");
    }

    private void SelectFirst(object sender, EventArgs e)
    {
        listView1.Items[0].Selected = true;
        listView1.Select();
    }

    private void SortAndSelect(object sender, EventArgs e)
    {
        listView1.Sorting = SortOrder.Ascending;
        listView1.Sort();

        listView1.Items[0].Selected = true;
        listView1.Select();
    }

Notice the listView1.Select()

You probably have HideSelection set to true. Make it false, and try.

myListView.HideSelection = false;

Furthermore listviews can have a selected item but with no focus on some other item. So its better to set both focus and selection together:

if (myListView.Items.Count > 0)
{
    myListView.Items[0].Selected = true;
    myListView.Items[0].Focused = true;
}

If that doesn't work you can set focus to listview itself to see if selection is falling on right item.
