{
myConnection = new SqlConnection("user id=sa;password=sa;initial catalog=pubs;data source=localhost");
if (!IsPostBack)
{
SqlDataAdapter myCommand = new SqlDataAdapter("select distinct State from Authors", myConnection);
DataSet ds = new DataSet();
myCommand.Fill(ds, "States");
MySelect.DataSource= ds.Tables["States"].DefaultView;
MySelect.DataBind();

[luckysusan]

没有指定DropDownList 的datatextfield和datavaluefield

[luckysusan]

MySelect.DataSource= ds.Tables["States"].DefaultView;
MySelect.DataTextField = "yourtextfieldname";
MySelect.DataValueField = "yourValuefieldname";
MySelect.DataBind();

[acewang]

MySelect.DataSource= ds.Tables["States"].DefaultView;
MySelect.DataTextField="xxx"
MySelect.DataValueField="xxx"
MySelect.DataBind()

[awcoin]

的datatextfield和datavaluefield
具体指的是什么啊

[awcoin]

protected void Page_Load(Object Src, EventArgs E)
{
myConnection = new SqlConnection("user id=sa;password=sa;initial catalog=pubs;data source=localhost");
if (!IsPostBack)
{
SqlDataAdapter myCommand = new SqlDataAdapter("select distinct State from Authors", myConnection);
DataSet ds = new DataSet();
myCommand.Fill(ds, "States");
MySelect.DataSource= ds.Tables["States"].DefaultView;
MySelect.DataTextField="states";
MySelect.DataValueField="states";
MySelect.DataBind();

}


这样还不行啊
