1) DataReader does not implement any specific interface so that it can
be bindable
2) DataReader is for reading data.So if some how u r able to bind
that,it won't allow u to edit that.So it's of no use.
3) DataReader is forward only,that means u can get a record at a time
but can't traverse back to the prev record.

This code shows how to bind gridview with data reader
Use this code on page load

 
void Page_Load(Object sender, EventArgs e)
{
  String Q;
  Sql command cmd;
  Sql DataReader dr;


  SqlConnection conn = new SqlConnection();

  conn.ConnectionString = ConfigurationManager.ConnectionStrings        ["cn"].ConnectionString.ToString();

conn.Open();
         
Q = "select * from tablename";
              
cmd= New Sqlcommand(Q, conn); 
         
dr = cmd.ExecuteReader();         
         
Gridview1.DataSource = dr;
           
Gridview1.DataBind();
}

When you bind Data reader to gridView


it iterates through  records one by one and All records Rendered One bye one in HTML Table row

so as a result you see data in Grid View .
