you can check if dr has any more recordset ot no by using if (dr.NextResult())

and then loop again with dr.read

try this

string connStr = ConfigurationManager.ConnectionStrings["ConString"].ConnectionString;
SqlConnection Con = new SqlConnection(connStr);

try
{
    string str1 = "select productid,productname from products;select VendorFName from vendor";
    SqlCommand com = new SqlCommand(str1, Con);

    com.Connection.Open();

    SqlDataReader dr = com.ExecuteReader();

    DropDownList1.Items.Add("Select Product Id");
    DropDownList2.Items.Add("Select Vendor Name");

    while(dr.Read())
    {
        DropDownList1.Items.Add(dr.GetValue(0).ToString());
    }

    if (dr.NextResult())
    {
        while (dr.Read())
        {
            DropDownList2.Items.Add(dr.GetValue(0).ToString());
        }
    }
}
catch (Exception ex)
{
}
finally
{
    if (Con.State == ConnectionState.Open)
    {
        Con.Close();
    }
}
