ลองดูนะครับ
หรือไม่ก็ดูตัวอย่างในหัวข้อซีชาปก็ได้มีเยอะนะครับ
Code (C#)
MySql.Data.MySqlClient.MySqlConnection objConn;
MySql.Data.MySqlClient.MySqlCommand objCmd;
public void Page_Load(object sender, EventArgs e)
{
string strConnString = null;
strConnString = "Server=localhost;User Id=root; Password=root; Database=mydatabase; Pooling=false";
objConn = new MySql.Data.MySqlClient.MySqlConnection(strConnString);
objConn.Open();
BindData();
}
public void BindData()
{
string strSQL = null;
strSQL = "SELECT * FROM customer";
MySql.Data.MySqlClient.MySqlDataReader dtReader = default(MySql.Data.MySqlClient.MySqlDataReader);
objCmd = new MySql.Data.MySqlClient.MySqlCommand(strSQL, objConn);
dtReader = objCmd.ExecuteReader();
//*** BindData to Repeater ***'
myRepeater.DataSource = dtReader;
myRepeater.DataBind();
dtReader.Close();
dtReader = null;
}
public void Page_UnLoad()
{
objConn.Close();
objConn = null;
}
