If the items are listed on consecutive lines in the RTB then try this (Windows Forms assumed): private void button1_Click(object sender EventArgs e) { if (richTextBox1.Text.Length > 0) { listBox1.Items.AddRange(richTextBox1.Lines); } } It's also assumed that if there are existing items in the ListBox these will be added to not overwritten.
