我想将数据绑定到dropdownlist中，可是下拉列表出现的是System.Data.....
为什么我用以下代码无法将数据绑定到下拉列表中呢？
private void Page_Load(object sender, System.EventArgs e)
{
ConnectionString=System.Configuration.ConfigurationSettings.AppSettings[ "ConnectionString "];
conn=new SqlConnection(ConnectionString);
if(!IsPostBack)
BindDropDownList();
}
private void BindDropDownList()
{
string strsql;
strsql= "select * from dep ";
ds=new DataSet();
da=new SqlDataAdapter(strsql,conn);
conn.Open();
da.Fill(ds, "Dep ");
dep_name.DataSource=ds.Tables[0].DefaultView;
dep_name.DataBind();
conn.Close();
}
[解决办法]
指定DataValueField和DataTextField
DdlStorage.DataSource = storage_table;
DdlStorage.DataValueField = "STORAGE_ID ";
DdlStorage.DataTextField = "STORAGE_NAME ";
DdlStorage.DataBind();
[解决办法]
dep_name.DataSource=ds.Tables[0].DefaultView;
//想在dropdownlist中显示的内容
dep_name.DataTextField = "XXX ";
//想在dropdownlist中保存的值的内容
dep_name.DataValueField = "YYY ";
dep_name.DataBind();
[解决办法]
这样写行吗？

这样应该可以了
