Hi, Are you developing desktop base application or web base application? agree with above answer if you are developing desktop application but approach is different when you use web application because web application is stateless and you have to maintain state by your self hope this will help you.

static int Num = 0; string Str = "C00"; string Stm; private void button1_Click(object sender, EventArgs e) { Num++; Stm = Str + Num.ToString(); ComboBox1.Items.Add(Stm); }

You can try this ocde: static int Num = 0; string Str = "C00"; string Stm; private void button1_Click(object sender, EventArgs e) { Num++; Stm = Str + Num.ToString(); MessageBox.Show(Stm); } Ans will be: C001 C002 C003 - - - - C0010
