Hi What item contains in ur combobox? not mentioned. I am assuming only text. To which u need to bind ur TextBox? I am assuming that too that selected text needs to be displayed. private void comboBox1_SelectedIndexChanged( object sender EventArgs e) { textBox1.Text = comboBox1.SelectedItem.ToString(); }
