Thanks and regards,

Hello Karsten,

Thank you for writing.

In order to select an item, pressing the key associated with the first letter of the item's text, it is appropriate to use the RadListView.PreviewKeyDown event. Here is a sample code snippet, demonstrating how to select the first found item, starting with the pressed key:

Keys savedKey;
Queue<ListViewDataItem> queue = new Queue<ListViewDataItem>();

void radListView1_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyData != savedKey)
    {
        queue.Clear();
        foreach (ListViewDataItem item in radListView1.Items)
        {
            if (item.Text.StartsWith(e.KeyData.ToString()))
            {
                queue.Enqueue(item);
            }
        }

        if (queue.Count > 0)
        {
            ListViewDataItem itemToSelect = queue.Dequeue();
            radListView1.SelectedItem = itemToSelect;
            queue.Enqueue(itemToSelect);
        }
        savedKey = e.KeyData;
    }
    else if (queue.Count > 0)
    {
        ListViewDataItem itemToSelect = queue.Dequeue();
        radListView1.SelectedItem = itemToSelect;
        queue.Enqueue(itemToSelect);
    }
}

I hope this information helps. Should you have further questions, I would be glad to help.
