復制代碼 代碼如下:

public void Page_Load(Object src.EventArgs e)
{
ArrayList arrValue = new ArrayList();
arrValue.add("kk");
arrValue.add("dd");
arrValue.add("aa");
arrValue.add("cc");
//將數組綁定到DropDownList控件的DataSource屬性
ddl.DataSource = arrValue;
ddl.DataBind();
}

復制代碼 代碼如下:

public void Page_Load(Object src.EventArgs e)
{
ddl.Items.Add(new ListItem("text","value");
ddl.Items.Add(new ListItem("text1","value1");
ddl.Items.Add(new ListItem("text2","value2");
}

復制代碼 代碼如下:

protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
string myconnstr="Provider=Microsoft.Jet.OLEDB.4.0;Data Source="+Server.MapPath(".")+"..//database//db.mdb";
OleDbConnnection myconn=new OleDbConnnection(myconnstr);
string sqlstr="select * from test";
OleDbCommand myComm = new OleDbCommand(sqlstr,myconn);
myComm.Connection.Open();
OleDbDataReader dr=myComm.ExecuteReader();
while (dr.Read())
{
bj.Items.Add(new ListItem(dr["bjmc"].ToString(), dr["id"].ToString()));//增加Item

//或者這樣也能綁定，
//DropDownList1.Items.Add( new ListItem( myReader[1].ToString(),myReader[0].ToString() ) );//增加Item
//都是要在知道Sql語句或者數據表結構的前提下才能這樣綁定
}
dr.Close();
}
}

復制代碼 代碼如下:

SqlConnection sqlconn = new SqlConnection();
sqlconn.ConnectionString = "workstation id=localhost;packet size=4096;user
id=sa;data source=db1;persist security info=False;initial catalog=DB";
sqlconn.Open();
SqlDataAdapter sqldar = new SqlDataAdapter("select UserName from forums_Users",sqlconn);
sqldar.SelectCommand.CommandType = CommandType.Text;
DataSet Ds= new DataSet();
sqldar.Fill(Ds,"Users");
ddl.DataSource = Ds.Tables["Users"].DefaultView;
ddl.DataTextField="UsersName";
ddl.DataBind();
sqlconn.Close();

復制代碼 代碼如下:

protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
string myconnstr="Provider=Microsoft.Jet.OLEDB.4.0;Data Source="+Server.MapPath(".")+"..//database//db.mdb";
OleDbConnnection myconn=new OleDbConnnection(myconnstr);
string sqlstr="select * from test";
OleDbCommand myComm = new OleDbCommand(sqlstr,myconn);
myComm.Connection.Open();
OleDbDataReader dr=myComm.ExecuteReader();
ddl.DataSource = dr;
ddl.DataBind(); 綁定倒DD1中
}
}

復制代碼 代碼如下:

DataBinder.eval_r(Container.DataItem,"表字段")
