double click on the first ddl in design view and the event will be setup for you (VS.Net). Let me know if you do not have VS.Net or VWD Express). VWD Express is free BTW.

private void DropDownList1_SelectedIndexChanged(object sender, System.EventArgs e){    //use sql to get ddl2 contents    string sql = "SOME QUERY TO FILL DDL2";    SqlConnection cnt = new SQLConnection("connection string");    SqlCommand cmd = new SqlCommand(sql,cnt);    SqlDataReader data;    cnt.Open();    data = cmd.ExecuteReader();    ddl2.DataSource = data;    ddl2.DataBind();    data.Close();    cnt.Close();}

That may have some syntax errors but you should be able to clean it up. This is assuming you are using SQL Server....change to ODBC or OleDb depending on your needs.NOTE: DropDownList1 must have AutoPostBack set to TRUE
