The Add() method return the index of rencently element added.

listBox1.SelectedIndex = listBox1.Items.Add(77);

First find the last inserted value from database by using select MAX(col.name) or select top 1 col.name (if you are using SQL Server), and store it in a string,or a label or something else, then use "listBox1.Items.FindByText()" to set focus on it...

string x;
sqlconnection con="...........";
con.open();
sqlcommand cmd = new sqlcommand("select top 1 (your columnname) from yourtable",con);
x = cmd.ExecuteScalar().ToString();
con.Close();

now you got the last inserted item,then 

if (listBox1.Items.FindByText(x)!= null)
    listBox1.Items.FindByText(x).Selected = true;

You could set the focus whenever you add a new item to the listbox as follows,

listBox1.Items.Add(77);
listBox1.SetSelected(listBox1.Items.IndexOf(77), true);

I failed to found any method for latest added item to ListBox. You can however save the last added item in some variable and then go through whole listBox and search for item with the same value (will work properly only if the value is unique). Something like this

listBox1.SelectedIndex = listBox1.Items.IndexOf(yourNumber);
