合并来自两个SQL表的数据以在两个TabPage中显示

Question

我在<form> Name:<br> <input type="text" name="name" required><br> Email:<br> <input type="email" name="email" required><br> Phone (Format: 999-999-9999):<br> <input type="tel" name="phone" required pattern="\d{3}[\-]\d{3}[\-]\d{4}"><br> Nature of comment:<br> <input type="checkbox" name="comment" value="Question"> Question <input type="checkbox" name="comment" value="Business Inquiry"> Business Inquiry <input type="checkbox" name="comment" value="Comment"> Comment <input type="checkbox" name="comment" value="Other"> Other <br> Comment:<br> <textarea></textarea><br> <input type="submit" value="Submit"> <form onsubmit="return confirm('Do you really want to submit the form?');"> </form> 中有一个简单的注册程序，而不是只显示WinForms中的记录我想将插入dataGridView的数据放入textBox }}。但是，除了tabControl已在table中为所有客户信息创建的SQL server之外，我还需要为联系信息创建另一个table，然后再显示它们在tabControl中（一个tabPage中的一般信息和另一个中的联系信息）。

我想知道如何连接在SQL Server中创建的两个表，因为每个客户端的每个记录都由两个表填充。

CREATE TABLE tblClientes (
ID int IDENTITY(1,1) PRIMARY KEY NOT NULL,
Nome varchar(255) NOT NULL,
Telefone varchar(255) NOT NULL,
Tipo varchar(255) NOT NULL, );

CREATE TABLE tblTelefone (
ID int NOT NULL,
Telefone varchar(255) NOT NULL,
PRIMARY KEY (ID));


string strConn= "Data Source=X\\X;Initial Catalog=X;User id=X;Password=X;";
string strCommtblCli = "SELECT * FROM tblClientes ORDER BY ID"; //table com informações gerais 
string strCommtblCon = "SELECT * FROM tblTelefone ORDER BY ID"; //table de contato

SqlConnection objConn;
SqlCommand objComm;
SqlCommandBuilder cmdbldr;
SqlDataAdapter dataAdapter = new SqlDataAdapter();
DataSet dataSet = new DataSet("tblClientes"); 
string strConn= "Data Source=X\\X;Initial Catalog=X;User id=X;Password=X;";
string strCommtblCli = "SELECT * FROM tblClientes ORDER BY ID"; //table com informações gerais 
string strCommtblCon = "SELECT * FROM tblTelefone ORDER BY ID"; //table de contato
