请教链接问题
页面上没有出现DataGrid1控件，webconfig是对的代码如下：
protected void Show_DataGrid1()
{
//从文件Web.config中读取连接字符串
string sqldb = ConfigurationSettings.AppSettings["ConnectionString"];
//连接数据库
SqlConnection Conn = new SqlConnection(sqldb);
//定义sql语句
String selsql = "select UserID,UserName,PassWord,Email,Role from tb_User";
//创建SqlDataAdapter对象,调用selsql
SqlDataAdapter myadapter = new SqlDataAdapter(selsql, Conn);
//创建并填充DataSet
DataSet ds = new DataSet();
myadapter.Fill(ds);
DataGrid1.DataSource = ds;
DataGrid1.DataBind();
//关闭Conn
Conn.Close();
